The prime minister of Croatia, officially the president of the government of the Republic of Croatia, is Croatia's head of government, and is de facto the most powerful and influential state officeholder in the Croatian system of government. Following the first-time establishment of the office in 1945, the 1990–2000 semi-presidential period is the only exception where the president of Croatia held de facto executive authority. In the formal Croatian order of precedence, however, the position of prime minister is the third highest state office, after the president of the Republic and the speaker of the Parliament.

The president of Croatia, officially the president of the Republic of Croatia, is the head of state, commander-in-chief of the military and chief representative of the Republic of Croatia both within the country and abroad. The president is the holder of the highest office in Croatia. However, the president is not the head of the executive branch as Croatia has a parliamentary system in which the holder of the post of prime minister is the most powerful person within the country's constitutional framework and everyday politics.
