Hrvoje (Vojko) Bartolović (15 June 1932 in Zagreb – 3 November 2005), who was a Croatian chess problemist.

The Croatian grandmaster of chess composition Hrvoje Bartolović was considered the best Croatian chess problematist, with the possible exception of Nenad Petrović. Since 1948 he has published more than 800 problems (81 of them in the FIDE album). Over 180 of them were awarded prizes (80 with 1st prize), about 120 with honourable mentions and 120 with commendations. He was appointed FIDE International Judge of Chess Composition in 1956 and Grand Master of Chess Composition in 1980. In 1965 he was world champion in the composition of double moves.

"Hrvoje Bartolović was a (mostly two mover) composer and international judge.
In 2005 Juraj Lörinc selected on his website 6 excellent problems of his, in various genres as an obituary. Another excellent two mover by Hrvoje Bartolović showing Zagoruiko in perfect presentation is quoted on his Wikipedia webpage.
He was, with Nenad Petrović, the best Croatian composer and a selection of 72 of his best problems was published in 1963 in the Yugoslav review "Problem".
