1084 Tamariwa, provisional designation 1926 CC, is a carbonaceous background asteroid approximately 27 kilometres in diameter from the central regions of the asteroid belt. It was discovered on 12 February 1926, by Soviet astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[19] The asteroid was named after female paratrooper Tamara Ivanova, who died at an early age.[2]
