Zababa (, dza-ba4-ba4, ) was a Mesopotamian god. He was the tutelary deity of the city of Kish and was regarded as a god of war. He was initially seen as a son of Enlil, though in Assyria during the reign of Sennacherib, he started to be viewed as a son of Ashur instead. The goddess Bau came to be viewed as his wife after her introduction to Kish in the Old Babylonian period.

The worship of Zababa is first documented in sources from the Early Dynastic period, including texts from both Kish and other cities in Mesopotamia, for example the Zame Hymns from Abu Salabikh. His importance declined in the Sargonic and Ur III period, but he regained a more prominent position in the Old Babylonian period. Through the first millennium BCE he was worshiped both in Babylonia and in Assyria.

No myths focused on Zababa are known, though he is referenced in an UD.GAL.NUN composition about the construction of Enlil's temple, in a number of legends about rulers of the Akkadian Empire, and in texts known from late copies such as Urash and Marduk and Enmesharra's Defeat.

Name Zababa's name was written in cuneiform as dza-ba4-ba4. In Early Dynastic sources the spelling dza7-ba4-ba4 also occurs, though it is agreed za7 was only an early form of the sign za. According to Gonzalo Rubio, the name has no plausible Sumerian or Semitic etymologies, and can be compared with other structurally similar theonyms such as Alala or Bunene. Piotr Steinkeller assumes he was originally worshiped by Akkadians, but states his name cannot be necessarily classified as originating in Akkadian or another Semitic language. However, such an origin has been proposed as a possibility by , though without a specific etymology.

Explanatory texts could provide Zababa's name with artificial Akkadian etymologies likely based on homophony, alternate readings of signs or literary allusions, such as "crusher of stones" (dā’iš abnī) or "lord of the lands" (bēlu mātātum).

Character Zababa was regarded as a war god. However, inscription on kudurru (decorated boundary stones) and lists of deities in treaties indicate his importance was often considered secondary compared to Ninurta and Nergal. In texts from the reign of Hammurabi of Babylon Zababa, rather than Ninurta, appears as the primary war god, which according to Walther Sallaberger represents a development reflecting the proximity between Babylon and his cult center, Kish. His warlike character was reflected in the epithet qarrādum rabium, "great hero", though qarrādum ("hero") was routinely used to refer to many warrior deities.

The eagle was considered Zababa's symbolic animal, though it is unclear how the nature of this connection was understood. On kudurru he was represented by a staff topped with an image of this bird.

A constellation named after Zababa was recognized in Mesopotamian astronomy, and its individual stars, presumed to correspond to parts of modern Aquila, Ophiuchus and Serpens, could be referred to as parts of his body and clothing, with some of the attested examples including "Crown of Zababa", "Eye of Zababa" (Eta Ophiuchi), "Shoulder of Zababa", "Middle of Zababa" (Nu Ophiuchi), "Shin of Zababa" (Eta Serpentis) and "Foot of Zababa" (Lambda Aquilae).

Associations with other deities Family and court Zababa could be regarded as a son of Enlil. Walther Sallaberger argues that it can be considered an example of a broader pattern of identifying warlike city gods as his sons, with other examples including Ningirsu and Nergal. In Assyria during the reign of Sennacherib Zababa started to be considered a son of Ashur instead. Wilfred G. Lambert assumed that much like contemporary references to Ninlil as Ashur's wife and Ninurta as another of his sons it is an example of assigning Enlil's family members to him to strengthen his new identity as the "Assyrian Enlil". A reference to Ashur being Zababa's father is known from Sennacherib's oracular inquiry meant to verify his parentage before the construction of a new temple dedicated to him and Bau in Assur, but this tradition is otherwise sparsely attested.

Bau, originally the wife of Ningirsu, could also be regarded as Zababa's wife. An early reference to this tradition can be found in the Lament for Sumer and Ur. In the god list An = Anum, Bau appears both in Zababa's (tablet V, line 48) and Ningirsu's (tablet V, line 56) sections. From the Middle Babylonian period onward, pairing her with Zababa became common. They appear as a couple in both Babylonian and Assyrian sources, for example in oath formulas and on kudurru. The pairing of Zababa with Bau reflects a broader archetypal pattern of couples consisting of a warrior god and a medicine goddess. Examples include Ningirsu and Bau, Ninisina and Pabilsaĝ, and Ninurta and Ninnibru.

Joan Goodnick Westenholz argues that before the introduction of Bau to Kish in the Old Babylonian period Inanna of Kish (to be distinguished from Inanna of Uruk) was regarded as Zababa's spouse. However, Ryan D. Winters points out that despite this assumption being commonly repeated in modern literature, no primary sources refer to them as a couple, and that texts where they appear together only affirm that both were both worshiped in Kish; he suggests it is not impossible that if a connection did exist between them, they might have equally likely been viewed as siblings in the local tradition instead. Andrew R. George states that listing them together simply reflected the fact they shared the role of the tutelary deity of Kish.

According to An = Anum, Papsukkal was regarded as Zababa's vizier (sukkal dza-ba4-ba4-ke4; tablet V, line 49). Frans Wiggermann argues that while late sources refer to him as a son of Anu and descendant of Enmesharra, he might have originally been viewed as Zababa's son. For uncertain reasons, Zababa's section in An = Anum also includes Ugur (tablet V, line 50), who fulfilled the analogous role in the court of Nergal.

Two minor goddesses, Iqbi-damiq ("she said 'it is fine!'") and Ḫussinni ("Remember me!"), were associated with Zababa's temple, Edubba, and could be referred to as the "daughters of Edubba". Other similar pairs, collectively referred to as "divine daughters" by Assyriologists, were assosicated with other temples of northern Babylonia, such as Emeslam in Kutha (Tadmuštum and Belet-ili), Eibbi-Anum in Dilbat (Ipte-bita and Belet-eanni), Ezida in Borsippa (Kanisurra and Gazbaba) and Esagil in Babylon (Katunna and Silluš-tab). Wiggermann suggests that they pair from Kish might have been regarded as children of Zababa and his wife. However, George instead assumes that all of the pairs of "divine daughters" were maidservants in the household of the major deity or deities of a given temple. Wiggermann also argues that a further member of Zababa's entourage, Kūbu (a deity regarded as a stillborn infant), might have been his child as well.

Udulu, "day of violent storm", usually a title of Zababa and other war gods, could also be regarded as a minor god belonging to his court, and in reference to this role could be depicted in the form of an eagle. Wiggermann states he presumably functioned as an enforcer of Zababa's will, and compares him with Papsukkal, though he stresses the latter was not associated with birds of prey.

Further members of Zababa's court are known from Late Babylonian texts from Babylon and Kish, and include the divine judge Mandanu, the Nergal-like minor god Luḫušû, and a number of deified weapons, such as Igalim, Shulshaga, Šaggāšu, Kami-tāmûšu ("who binds the one who swears by him"; already attested in the Old Babylonian period), Muštēšir-ḫabli, Kakku-Šazu, Kakku-SAĞ.NINNU (or Kakku-SAĞ.PIRIĞ), Sharur and Shargaz, some of which were also associated with other gods. For instance, Igalim and Shulsaga were originally Ningirsu's sons, while Sharur and Shargaz - Ninurta's weapons.

Identification with other Mesopotamian deities Zababa's character has been compared to Ninurta's. A degree of overlap is attested between their courts, and like Ninurta Zababa could be called the "crusher of stones" (dā’iš abnī), as attested in Bulluṭsa-rabi's Hymn to Gula. Sometimes, as attested for example in the Epic of Anzû (tablet III, line 32), the two could be equated. In the text KAR 142, the Archive of Mystic Heptads, Zababa is listed as one of the "seven Ninurtas", though in this context this name is a generic designation for warlike deities. In kudurru inscriptions and treaties, Zababa occurs separately from Ninurta, as a god of lesser importance.

The Syncretic Hymn to Marduk (tablet BM 47406) refers to Zababa as "Marduk of warfare". Beate Pongratz-Leisten argues that this reflects the absorption of other deities by the latter, and compares this process to the rise of Yahweh to prominence. However, Spencer J. Allen suggests that similar statements might be metaphorical, and that their aim was not outright equating Marduk with other gods, but rather comparing him to them to portray him as equally capable as them. In Zababa's case this would correspond to extolling Marduk as a similarly warlike figure.

Identification with foreign war gods In Bronze Age Anatolia, Zababa's name was used as a logogram ("Akkadogram") to represent the names of multiple other gods of similar warlike character. Walther Sallaberger assumes that this convention developed due to the influence of the First Dynasty of Babylon. Alice Mouton assumes that in Hattian and Hittite context Zababa's name designated Wurunkatte and less commonly Šulinkatte, in Hurrian Aštabi, Nupatik and Ḫešui, and in Luwian possibly Iyarri. However, according to interpreting dZA.BA4.BA4 as a logographic representation of Nupatik's name is erroneous, and in the Hurrian context it consistently refers to Ḫešui, with dLAMMA designating Nupatik instead. According to Alfonso Archi Aštabi's name was written as dNIN.URTA in Hurrian sources. However, Aštapinu, presumed to be a variant spelling of Aštabi is identified with both Zababa and Ninurta in the Mesopotamian god list informally referred to as "shorter An = Anum" due to sharing its namesake's first line, but not its scope. He is defined in it as the counterpart of these gods in Subartu, a common designation for northern areas, which according to Ryan D. Winters reflects the attested geographic distribution of references to his cult.

Wouter Henkelman proposes that the theonym Nabbazabba known from the Persepolis Fortification Archive might be an Elamite derivative of Zababa's name, possibly to be interpreted as "the god Zabba".

Worship Third millennium BCE Zababa was the tutelary god of the city of Kish, as already attested in the oldest known source mentioning him, an early inscribed plaque. It dates to Early Dynastic II period ( 2750-2600 BCE), and records prisoners of war most likely assigned to work on a date palm plantation and their points of origin. Zababa is mentioned in the final section of the text, which contains a brief reference to Kish, where the document presumably originated.

Based on archeological evidence it is assumed that a temple of Zababa already existed in Kish in the Early Dynastic period. Later sources indicate it bore the ceremonial Sumerian name Edubba, "storage house". It could also be referred to as Emeteursag, "house worthy of the hero", though in later periods this ceremonial name was only used to a cella located within as opposed to the entire complex.

Zababa was also known outside Kish, further south in lower Mesopotamia. It is presumed that he was considered a major deity across the region in the Early Dynastic period. A reference to him has been identified in an inscription of Uḫub, an Early Dynastic ruler (ensi) of Kish, discovered in Nippur.
