The electoral colleges for the Senate (Dutch: kiescolleges voor de Eerste Kamer; Papiamentu: kolegionan elektoral pa Eerste Kamer) are the electoral colleges of the Caribbean Netherlands and Dutch expatriates. Their members together with the members of the provincial councils in the European Netherlands choose the Senators of the Dutch Senate.
The first electoral college elections (then only in the Caribbean Netherlands) were held on 20 March 2019, simultaneously with the island council elections, and the European Netherlands' provincial elections and water board elections. On 27 May 2019, the colleges cast their votes for the Senate election.
