2021 Køge municipal election

For this election, Marie Stærke from the Social Democrats was seeking re-election and a fourth term, after having won the mayor's position following the last election.

In the election result, the Social Democrats would be the largest party with 10 seats against second-place Venstre who won 6 seats.

Other parties in the agreement, included - the Green Left, Danish People's Party and the Red–Green Alliance.
