At least five people were gravely injured in the attack, which took place in the Sultangazi neighborhood of the capital city, Agence-France Press cited local media as saying.
Istanbul police chief Huseyin Capkin told journalists the attacker "threw a grenade, then blew himself up at the entrance of the police station," Reuters said.
The Associated Press cited Capkin as saying the bomber was 25 years old.
No group has claimed responsibility.
Such attacks are relatively rare in Turkey. AFP said the last suicide bombing seen in the country took place in Kayseri in May and was claimed by the banned Kurdistan Workers Party, with whom Turkey has been fighting a deadly guerilla war for decades.
However, violence between the two groups has escalated in recent months, according to AP.
