Greens' candidate Sibylle Keupen won more than two thirds of the vote in Aachen, on the border with Belgium and the Netherlands.
In Bonn, the former German capital, Green party national lawmaker Katja Doerner ousted the incumbent mayor from Chancellor Angela Merkel's Christian Democrats.
Greens candidate Uwe Schneidewind won the runoff against the centre-left Social Democrat incumbent in the industrial city of Wuppertal.

This is the first time the party has won mayoral elections in the state, which is Germany's most populous.
