Josef Čihák (born 19 March 1963) is a former professional tennis player from the Czech Republic who competed for Czechoslovakia.

He now works as a tennis coach at TK Sparta Prague.

As well reaching those two finals in 1989, Čihák was also a semi-finalist at the Athens Open, in the singles.

The toughest opponent he came up against was Mats Wilander in the 1988 French Open, the number three seed who went on to win the tournament.

In doubles he won four of his 10 matches, but never made it past the second round, which he reached on four occasions, three times with countryman Cyril Suk as his partner.
