The national flag of Lebanon () is a horizontal triband of two red stripes enveloping a central white stripe which is twice the height of each red stripe. Centered on the white stripe is a green cedar of Lebanon tree (Cedrus libani), touching both red stripes.

Adopted on 7 December 1943, shortly before Lebanon gained independence from France, the flag's design reflects the country's geography, history, and cultural heritage. The red stripes are commonly interpreted as symbolizing the blood shed by the Lebanese people during their struggles for independence, while the white stripe represents peace, purity, and the snow-capped mountains of Lebanon. The cedar tree, a national symbol for centuries, stands for immortality, resilience, and hope, embodying Lebanon's identity as the "Land of the Cedars".

The flag's origins trace back to the early 20th century, with the cedar tree becoming a prominent symbol during the French mandate period. The current design was finalized during a tense political climate in 1943, when Lebanon unilaterally abolished the French mandate. The flag was formally introduced into the Lebanese Constitution on 7 December 1943, with its design standardized in 1990 to feature an entirely green cedar tree. In 1979, 21 November was declared as National Flag Day to honor the first flag-raising in 1943.

Design

According to the Article 5 of the Constitution of Lebanon, adopted on 7 December 1943: "The Lebanese flag shall be composed of three horizontal stripes, a white stripe between two red ones. The width of the white stripe shall be equal to that of both red stripes. In the center of and occupying one third of the white stripe is a green Cedar tree with its top touching the upper red stripe and its base touching the lower red stripe."

The constitution does not provide any additional color and design specifications, and before the amendment of the constitution on 21 September 1990, it also did not specify the color of the cedar tree, leading to variations in practice. Traditionally, as long as the essential colors and symbols are present, artistic interpretations are acceptable. Before 1990 the cedar tree on the Lebanese flag was commonly depicted with a brown trunk; similar brown-trunk variants were registered by the World Intellectual Property Organization (WIPO) and on official postcards of United Nations with member state flags. The 1990 amendment specified that the entire cedar tree must be green.

Symbolism

The cedar of Lebanon holds a prominent place in history and religious texts. It is mentioned 103 times in the Bible, often symbolizing the glory of strength, majesty, and divine blessing. In Psalms 92:12, it is written, "[t]he righteous will flourish like a palm tree, they will grow like a cedar of Lebanon", and in Psalms 104:16, "[t]he trees of the Lord are well watered, the cedars of Lebanon that he planted". The cedar's wood, known for its durability and resistance to pests, was used to build sacred structures, including Solomon's Temple in Jerusalem. Its significance extends beyond biblical narratives into ancient Mesopotamian literature, where it plays a pivotal role in the Epic of Gilgamesh as divine wood guarded in a sacred forest. Ancient Egyptians particularly valued Lebanese cedar, using its resin in mummification processes and its wood in shipbuilding and ceremonial barges, as evidenced by cedar planks found near the Great Pyramid of Giza.

The cedar has inspired writers, poets, and political leaders. The French author and statesman Alphonse de Lamartine, marveling at the cedars during his trip to Lebanon in 1832, wrote, "[t]he cedars of Lebanon are the relics of centuries and nature, the most famous natural landmarks in the universe." Similarly, the French writer and aviator Antoine de Saint-Exupéry, who visited Lebanon in 1935, reflected on the cedar's symbolism in his work : "[t]he peace is a long-growing tree. We need, as the cedar, to rock its unity." In 1920, during the proclamation of the State of Greater Lebanon, the cedar was described as a symbol of resilience and unity: "[a]n evergreen cedar is like a young nation despite a cruel past. Although oppressed, never conquered, the cedar is its rallying. By the union, it will break all attacks."

Writing in 1926, the Lebanese-born Jesuit Pierre Raphaël emphasized the cedar's role as a unifying national symbol during the French Mandate period, when the flag featured a cedar on a French tricolor background. He described the cedar as "a witness of the past, present and future," calling for all Lebanese to 'hold it high' as a symbol of national pride worthy of ultimate sacrifice. While interpreting the French inspired flag symbolism in a Lebanese context, he associated the blue with the Phoenician maritime legacy and 'the horizon of peace and heaven of liberty,' the white with Lebanon's snow-capped mountains and principles of justice and faith, and the red with both Phoenician purple and ancestral blood shed for traditions. Some of these symbolic associations, would later carry over into interpretations of the current flag design, which was adopted in 1943.

Interpretations of the current flag's colors vary. Some accounts link the red and white to the historical conflict between the Qaysi and Yamani factions, with red representing the Qaysi and white the Yamani. The combination of these colors with the cedar is seen as a resolution of Lebanon's divisions and a symbol of national unity. Vexillologist Whitney Smith, in Flags and Arms Across the World, supports this interpretation. Broader symbolism associates white with the snow cap of the Lebanon mountains, purity, peace, and spiritual authority, red with sacrifice, and strength, and green with hope and renewal. The green cedar stands for immortality, steadfastness, and hope, serving as a unifying national symbol. For Christians, green represents hope, while in Islamic tradition, it signifies salvation.

Protocol The protocol governing the use and display of the flag of Lebanon is outlined in Decree No. 4081, originally issued on 2 August 1944 and amended twice: first on 12 June 1959 during the presidency of Fouad Chehab, and again on 14 October 2000 under President Émile Lahoud. The 2000 amendment was prompted by the absence of unified standards for state ceremonies and protocols. This decree, rooted in the Lebanese Constitution and informed by earlier decrees related to state protocol and the organization of the Ministry of Foreign Affairs, establishes specific guidelines for the flag's display in official, diplomatic, and ceremonial contexts. In 2019, a proposal was introduced to further amend the protocols, with the intention of implementing the updates in 2020. The proposed changes aimed to modernize Lebanon's ceremonial practices, enhancing precision, addressing contemporary needs, and ensuring alignment with evolving national and international standards while maintaining the foundational principles of Lebanese traditions. However, as of 2025, these updates have not yet been formally put into effect.

Display

The Lebanese flag is prominently displayed in the offices of the President, the Speaker of Parliament, the Prime Minister, and Lebanese ambassadors abroad, with a large flagpole placed to the right of the desk in these offices. A portrait of the President featuring the flag is also displayed in the offices of high-ranking officials, meeting halls of ministries, embassies, consulates, public institutions, and security agencies. The flag is raised daily from sunrise to sunset on all official government buildings, border stations, airports, and seaports, and remains raised day and night at the Presidential Palace while the President is in Lebanon. It is displayed on the right side of the President's vehicle and the front right side of the vehicles of the Speaker of Parliament and the Prime Minister. The display of faded or torn flags is prohibited, and the flag is flown at half-mast during periods of mourning, as directed by the Prime Minister's Office.

When displayed alongside foreign flags, the Lebanese flag takes precedence. It is positioned in the center when raised with multiple foreign flags within Lebanon. During official visits by foreign heads of state, their national flag is displayed at the reception venue and their residence, with the Lebanese flag to its left. On vehicles, the foreign flag is displayed on the right side, while the Lebanese flag is displayed on the left. No foreign flag may be displayed above the Lebanese flag.

Ceremonial use The flag plays a central role in state ceremonies and official visits. During the presentation of credentials by a new ambassador, the flag of the ambassador's country is raised to the right of the Lebanese flag in the courtyard of the Presidential Palace. The ambassador is escorted in a motorcade with their national flag on the right side of the vehicle and the Lebanese flag on the left. Upon arrival, the ambassador is greeted with military honors, and the national anthems of both countries are played. The flag is also draped over the coffins of deceased high-ranking officials, including former presidents, during state funerals. The funeral processions, accompanied by military honors, feature the flag prominently as a symbol of national mourning and respect.

During state visits, the Lebanese flag and the flag of the visiting dignitary's country are displayed prominently at the arrival venue and along the motorcade route. The visiting dignitary is greeted with a 21-gun salute and a military guard of honour. The national anthems of both countries are played, and the dignitary inspects the guard of honor, pausing to bow before the Lebanese flag as a sign of respect. The flag is also used to adorn the venue for official receptions and state dinners hosted in honor of the visiting dignitary.

History The cedar tree has long been a symbol of Lebanon, with its roots tracing back to the 18th century when it became emblematic of the Maronites, an Eastern Catholic community originating from the Levant. The first recorded use of the Maronite flag – a white field charged with a green cedar tree – was in October 1848, reflecting the cedar's growing significance as a national symbol.

Early national consciousness (1907–1913)

The development of a Lebanese flag emerged from growing national consciousness in the early 20th century. At this point in history, Mount Lebanon was a semi-autonomous district (Mutasarrifate) under the Ottoman Empire. Despite the empire's overarching rule, local councils such as the Administrative Council of Mount Lebanon were pushing for more autonomy and recognition of the unique sociopolitical and religious identity of Mount Lebanon's primarily Christian population – particularly the Maronites. In Mount Lebanon, members of the Administrative Council began pursuing a "Lebanese policy" to achieve greater sovereignty of the Mount Lebanon Mutasarrifate within the Ottoman Empire.

In 1907, , a Lebanese Brazilian journalist, proposed in "Les Trésors cachés du Liban" that Lebanon could add a cedar branch to the Ottoman flag as recognition of Lebanese privileges. The Committee for the Defense of Lebanese Interests emphasized Lebanon's "distinct personality" from Syria, citing centuries of historical privileges that neither Arab invasion nor Turkish domination could eliminate. In 1913, El Khoury, publishing from Brazil in his journal Le Sphynge, proposed a white flag with a central cedar, which was adopted by Lebanese emigrants in America and consequently presented to Allied Powers representatives.
