Otto John Jelinek (born May 20 1940) is a businessman and former figure skater and Canadian politician.

Jelinek's family fled to Canada from Czechoslovakia in 1948 at the beginning of the Cold War. He and his sister, Maria , became figure skaters and achieved prominence in 1962 when they won the gold medal at the World Figure Skating Championships which was held that year in Jelinek's birthplace of Prague. The pair had been warned not to return but did so anyway. The pair were the first to perform lifts with several rotations and also performed side-by-side double jumps.

After a time in business, Otto Jelinek entered politics and was elected in the 1972 Canadian election to the House of Commons as the Progressive Conservative MP for High Park-Humber Valley in Metropolitan Toronto. He was re-elected in 1974 before switching to the riding of Halton where he ran and won in the 1979 federal election.

When the Tories won government in the 1984 election Prime Minister Brian Mulroney appointed Jelinek to Cabinet as Minister of State for Fitness and Amateur Sport as well as for Multiculturalism. In 1988 he was promoted to Minister of Supply and Services before becoming Minister of National Revenue. Jelinek left politics after Mulroney retired and did not run in the 1993 Canadian election.

In politics, Jelinek was considered a right wing conservative and a staunch anti-Communist.

In 1994 he moved to the Czech Republic becoming Chairman of the Board of Directors of Deloitte & Touche Central Europe and Chairman and Managing Partner of the firm in the Czech Republic.
