An indirect presidential election (officially the 7th Federal Convention) was held in West Germany on 23 May 1979. Deeming his reelection to be unlikely, incumbent Walter Scheel elected not to seek a second term. The two candidates to replace him were the president of the Bundestag, Karl Carstens, nominated by the Christian Democratic Union, and Carstens' immediate predecessor, Annemarie Renger, nominated by the Social Democratic Party. Carstens won the election on the first ballot.
