Alexander Lvovich Rosenberg ( Russian: Александр Львович Розенберг, 1946–2012) ^[2] was a Russian-American mathematician who worked on functional analysis, representation theory and noncommutative algebraic geometry. ^[3] He graduated from Lomonosov Moscow State University in 1973, left the Soviet Union around 1987, and was a professor at Kansas State University until 2012.

He is known for his contributions to Tannaka duality and noncommutative algebraic geometry. He introduced several notions of spectrum for an abelian category (Rosenberg's spectrum), and the related Gabriel-Rosenberg reconstruction theorem bears his name. ^[4]
