With 30% of the vote, the SPD emerged as the largest party on a modest swing. The opposition Christian Democratic Union (CDU) remained steady on 26% but fell to second place. The Greens suffered a significant decline to 12%, while The Left repeated its 2019 performance of 11%. The right-wing Citizens in Rage (BiW) achieved their best-ever result with 9.4%, benefitting from the absence of the Alternative for Germany (AfD), who were disqualified from running due to internal party disputes. The Free Democratic Party (FDP) narrowly retained their seats with 5.1%.^[2][3]

On 25 June, the incumbent governing coalition announced that they would renew their cooperation, forming the Second Bovenschulte senate.

According to Bremen state constitution, the Bürgerschaft has a term of four years, and elections must take place on a Sunday or public holiday during the last month of the previous term.^[4] Bremen is the only German state whose parliament sits for a four-year term; all others have terms of five years. The previous election took place on 26 May 2019, and the date for the 2023 election was set for 14 May.^[1]

The Bürgerschaft is elected via open party-list proportional representation in two multi-member constituencies corresponding to the two parts of the state: the city of Bremen and the city of Bremerhaven. A five percent electoral threshold is applied independently in both areas. 72 members are elected in Bremen and 15 in Bremerhaven, for a total of 87 seats in the Bürgerschaft. Seat distribution is calculated using the Sainte-Laguë method. Voters each have five votes which may be distributed between party lists and the candidates within them; voters may cast multiple votes for a single candidate or list (panachage with cumulative voting). In Bremen (but not Bremerhaven), the same ballot is also used to elect the city council, also consisting of 72 members elected from the same pool of parties and candidates.^[5]

All German citizens aged 16 years or older who have lived in Bremen for at least three months are eligible to vote. Additionally, EU citizens residing in the city of Bremen and meeting the same requirements may vote, but their votes only count toward the Bremen city council election, not the state Bürgerschaft. Due to this, results for the Bremen city council may vary slightly from the state election results.^[5]

In the previous election held on 26 May 2019, the CDU became the largest party in the Bürgerschaft for the first time in post-war history, winning 26.7%. The SPD, which has governed the state continuously since the Second World War, was reduced to second place on 24.9%, a record low for the party and down eight percentage points from the 2015 election. The Greens and Left both improved modestly, taking 17% and 11% respectively, while the AfD and FDP won 6% each with slight losses. Citizens in Rage (BiW) retained its single seat in Bremerhaven.

The previous governing coalition of the SPD and Greens lost its majority in the election. Despite the CDU achieving a plurality, the Bürgerschaft retained an overall left-wing majority of the SPD, Greens, and Left. The three parties subsequently formed a coalition government under new mayor Andreas Bovenschulte, marking the first time The Left had entered government in a western state.^[6]

The table below lists parties represented in the previous Bürgerschaft of Bremen.

In March 2023, the state electoral committee disqualified the Alternative for Germany from running in the election due to the attempts of two different groups of party officials, both claiming to be the legitimate party executive, submitting competing lists.^[7]

Besides parties represented in the outgoing Bürgerschaft, ten parties ran in the election:

• Grassroots Democratic Party of Germany (dieBasis)
• Basic Income for All (GFA)
• Marxist–Leninist Party of Germany (MLPD)
• MeRA25
• Ecological Democratic Party (ÖDP)
• Die PARTEI
• Human Environment Animal Protection (Tierschutzpartei)
• Pirate Party Germany
• Volt Bremen
• Party for Biomedical Rejuvenation Research

Of these, all except the ÖDP and Pirate Party ran lists in Bremen only. The ÖDP ran lists in both Bremen and Bremerhaven, while the Pirate Party ran only in Bremerhaven.
