General elections were held in Belgium on 20 November 1921. The result was a victory for the Catholic Party, which won 70 of the 186 seats in the Chamber of Representatives. Voter turnout was 91.1% in the Chamber election and 91.0% in the Senate election. Elections to the nine provincial councils were held one week later, on 27 November 1921. A Catholic–Liberal government led by Georges Theunis was formed following the elections.
