List of members of the Senate of the Netherlands, 2019–2023

Between 11 June 2019 and 6 June 2023, 91 individuals served as representatives in Senate, the 75-seat upper house of the States-General of the Netherlands. 75 members were elected in the 27 May 2019 Senate election, and 16 members were appointed as replacements as elected representatives resigned or went on leave. Jan Anthonie Bruijn was elected President of the Senate on 2 July 2019.

During this period, the Third Rutte cabinet and Fourth Rutte cabinet reigned. Both coalitions where made up People's Party for Freedom and Democracy (VVD, 12 seats), Christian Democratic Appeal (CDA, 9 seats), Democrats 66 (D66, 7 seats) and Christian Union (CU, 4 seats). Totalling 32 seats, the coalition never had a majority in the Senate during this period.

The opposition consisted - at the start - of Forum for Democracy (FvD, 12 seats), GroenLinks (GL, 8 seats), Labour Party (PvdA, 6 seats), Party for Freedom (PVV, 5 seats), Socialist Party (SP, 4 seats), Party for the Animals (PvdD, 3 seats), 50PLUS (50+, 2 seats), Reformed Political Party (SGP, 3 seats) and Independent Politics Netherlands (OSF, 1 seat).

Resignations generally do not affect the balance of power, as replacements are appointed from the party list. However, during the term three new parliamentary groups were created, all split off Forum for Democracy. In July–August 2019, Henk Otten, Jeroen de Vries and Dorien Rookmaker left to form the Fractie-Otten. In February 2020, Rookmaker left and was replaced by Otto Hermans who joined the Forum for Democracy group again. In November–December 2020, another 8 members left Forum for Democracy, to form the Fractie-Van Pareren, which was later renamed Fractie-Nanninga. When Nicki Pouw-Verweij (member of the Fractie-Nanninga) left the Senate, she was replaced by Theo Hiddema who joined the Forum for Democracy group. Finally, in March 2022, Paul Frentrop and Theo Hiddema left Forum for Democracy to form the Fractie-Frentrop. This left Forum for Democracy at the end of the term with only one seat.
