Since 13 June 2023, 89 individuals have served as representatives in the Senate, the 75-seat upper house of the States-General of the Netherlands. After the 30 May 2023 Senate election, 75 members were elected and installed at the start of the term. There were 12 replacements during the term, some of them temporary. Jan Anthonie Bruijn was elected as President of the Senate at the start of the time. When he left in 2025, Mei Li Vos was elected as President of the Senate.
At the start of the term, the Farmer–Citizen Movement (BBB) was the largest party with 16 seats. GroenLinks (GL, 7 seats) and the Labour Party (PvdA, 7 seats) formed a joint parliamentary group at the start. The parliamentary group was named GroenLinks-PvdA and in 2026 renamed Progressief Nederland (Pro). The other parties in the Senate at the start of the term were People's Party for Freedom and Democracy (VVD, 10 seats), Christian Democratic Appeal (CDA, 6 seats), Democrats 66 (D66, 5 seats), Party for Freedom (PVV, 6 seats), Party for the Animals (PvdD, 3 seats), JA21 (3 seats), Socialist Party (SP, 3 seats), Christian Union (CU, 3 seats), Forum for Democracy (FvD, 3 seats), Volt (2 seats), Reformed Political Party (SGP, 2 seats), 50Plus (50+, 1 seat) and Independent Politics Netherlands (OPNL, 1 seat).
During the term, several members switched their parliamentary group affiliation, changing the party composition of the Senate. Eric Kemperman left BBB in May 2025 and continued as an independent until he joined FvD in September 2025. Robert Croll left BBB to join D66 in June 2025, and was later joined by Arie Griffioen in November 2025. Pim Walenkamp was not allowed to join the BBB group when he returned to the Senate in September 2025. Cees van de Sanden left VVD in October 2025. A conflict within the PvdD parliamentary group led to Ingrid Visseren-Hamakers leaving and continuing as independent, although Peter Nicolaï and Niko Koffeman were no longer member of the party. Toine Beukering entered the Senate as replacement on the JA21 candidate list in November 2025, but didn't join the parliamentary group. In March 2026, Robert van Gasteren was expelled from the BBB parliamentary group, after he cancelled his party membership, and continued as an independent. Because of these changes, this term had a record twenty parliamentary groups.
