Predrag Ostojić (22 February 1938 – 5 July 1996) was a Yugoslav chess player.

Tournament victories include equal 1st place at Vrnjačka Banja 1975, 1st at Paris 1968, 1969 and 1970, San Juan 1971, Casablanca 1974, Hasselt 1974.

When the creation of the International Association of Grandmasters was announced in Brussels (1987), Ostojić, on behalf of the Yugoslav chess players, offered Bobby Fischer the position of honorary chairman of the board, because he “was not only a brilliant chess player, but also a pioneer in the creation of professional chess.” Ostojić hoped to invite the American to act as a World Cup commentator, but all his initiatives remained unanswered.

[2] After the collapse of Yugoslavia and civil wars between the peoples of the formerly united country, he began to suffer from depression, which he fought with trips to the casino.
