Branko Zorko (born July 1, 1967 in Hodošan) is a Croatian middle distance runner, a notable 1500 m competitor in the 1990s. Probably his biggest accomplishment is winning the first international medal for the country of Croatia, winning a bronze medal at the 1992 European Indoor Athletics Championships. His other major sports achievements include:
- 6th place at the 1989 IAAF World Indoor Championships (3000 m)
- Bronze medal at the 1992 European Indoor Championships in Athletics
- Bronze medal at the 1993 IAAF World Indoor Championships
- Silver medal at the 1994 European Indoor Championships in Athletics
- Bronze medal at the 1994 European Championships in Athletics
- 4th place at the 1997 IAAF World Indoor Championships
- 4th place at the 2002 European Indoor Athletics Championships
By the late 1990s, Zorko was increasingly suffering from injuries, which prompted him to turn to professional pacemaking. As a pacemaker, he assisted in setting several world records, both indoors and outdoors, most notably for Haile Gebrselassie.
On July 11, 2005 at IAAF Grand Prix Zagreb, Zorko announced his retirement from competitive running.
