The Starry sturgeon (Acipenser stellatus), also known as Drakul and (Turkish) Uzun Burun (long nosed), is a species of sturgeons, living in the Black, Azov, and Caspian sea basins. It is rare in the Adriatic Sea. It reaches 220 cm (over 7 feet) and weighs up to 80 kg (approximately 180 Lbs). The maximum reported age for this species is 27 years. The starry sturgeon is a harmless species.

It is an important commercial species. It is one of the three most important species for caviar along with the Beluga sturgeon and the Persian sturgeon. Its flesh is considered an expensive delicacy in the Caspian region. It is used to make kababs, or is consumed pan fried, broiled, or smoked. There have been several attempts in Russia, Iran, Italy, and the US to adapt this species for aquaculture, with varying degrees of success.

The resilience of this species is low. The minimum population doubling time is 4.5 - 14 years.

The starry sturgeon is an endangered species and trade in products made from its body parts are restricted by CITES
