History The 8th constituency (Ptuj) was one of the eight constituencies established by the Determination of Constituencies for the Election of Deputies to the National Assembly Act (ZDVEDZ) () passed by the Assembly of the Republic of Slovenia () in September 1992. It consisted of the municipalities of Gornja Radgona, Lenart, Lendava, Ljutomer, Murska Sobota, Ormož, Pesnica and Ptuj.

Following the re-organisation of municipalities in October 1994, parts of Gornja Radgona municipality were transferred to the newly created municipalities of Radenci and Sveti Jurij; parts of Lendava municipality were transferred to the newly created municipalities of Črenšovci, Kobilje, Odranci and Turnišče; parts of Murska Sobota municipality were transferred to the newly created municipalities of Beltinci, Cankova–Tišina, Gornji Petrovci, Hodos–Sal, Kuzma, Moravske Toplice, Puconci and Rogašovci; parts of Pesnica municipality were transferred to the newly created municipalities of Kungota and Šentilj; and parts of Ptuj municipality were transferred to the newly created municipalities of Destrnik–Trnovska Vas, Dornava, Gorišnica, Juršinci, Kidričevo, Majšperk, Videm and Zavrč.

In August 1998 parts of Cankova–Tišina municipality were transferred to the newly created Tišina municipality whilst Cankova–Tišina was renamed Cankova; parts of Črenšovci municipality were transferred to the newly created Velika Polana municipality; parts of Destrnik–Trnovska Vas municipality were transferred to the newly created municipalities of Sveti Andraž v Slovenskih Goricah and Trnovska Vas whilst Destrnik–Trnovska Vas was renamed Destrnik; parts of Hodos–Sal municipality were transferred to the newly created Šalovci municipality whilst Hodos–Sal was renamed Hodos; parts of Kuzma municipality were transferred to the newly created Grad municipality; parts of Lenart municipality were transferred to the newly created municipalities of Benedikt, Cerkvenjak and Sveta Ana; parts of Lendava municipality were transferred to the newly created Dobronak municipality; parts of Ljutomer municipality were transferred to the newly created municipalities of Križevci, Razkrižje and Veržej; parts of Majšperk municipality were transferred to the newly created Žetale municipality; parts of Ptuj municipality were transferred to the newly created municipalities of Hajdina and Markovci; and parts of Videm municipality were transferred to the newly created Podlehnik.

In February 2021 the National Assembly passed Amendments and Supplements to the Determination of Constituencies for the Election of Deputies to the National Assembly Act (ZDVEDZ-B) () which defined the Ptuj constituency as consisting of the municipalities of Apače, Beltinci, Benedikt, Cankova, Cerkvenjak, Cirkulane, Črenšovci, Destrnik, Dobronak, Dornava, Gornja Radgona, Gornji Petrovci, Gorišnica, Grad, Hajdina, Hodos, Juršinci, Kidričevo, Kobilje, Križevci, Kuzma, Kungota, Lenart, Lendava, Ljutomer, Majšperk, Markovci, Moravske Toplice, Murska Sobota, Odranci, Ormož, Pesnica, Podlehnik, Puconci, Ptuj, Radenci, Razkrižje, Rogašovci, Šalovci, Šentilj, Središče ob Dravi, Sveti Tomaž, Sveta Ana, Sveta Trojica v Slovenskih Goricah, Sveti Andraž v Slovenskih Goricah, Sveti Jurij, Sveti Jurij v Slovenskih Goricah, Tišina, Trnovska Vas, Turnišče, Velika Polana, Veržej, Videm, Zavrč and Žetale.

Electoral system Ptuj currently elects 11 of the 90 members of the National Assembly using the open party-list proportional representation electoral system. Each constituency is divided into 11 electoral districts () in which each party stands a single candidate. Electors vote for a candidate of their choice in their electoral district and then the votes received by each party's candidates are aggregated at the constituency level.

Allocation of seats was carried out in two stages. In the first stage, seats are allocated to parties at the constituency level using the Droop quota (Hare quota prior to 2006). In the second stage, unallocated seats from the first stage are aggregated at the national level and allocated to parties using the D'Hondt method (any seats won by the party at the constituency level are subtracted from the party's national seats). Though calculated nationally, national seats are allocated at the constituency level.

Since 2000, only parties that reach the 4% national threshold compete for seats at both constituency and national levels. Prior to this there was no threshold at the constituency level but parties needed to reach (c3.4%) to compete for seats at the national level.

Seats won by each party in a constituency are allocated to the candidates with the highest percentage of votes. As a consequence, multiple candidates may be elected from an electoral district whilst others may have no candidates elected. Prior to 2000 parties had the option to have up to 50% of their national seats allocated in the order they appear on their party list (closed list).
