Sinemorets Hill (Halm Sinemorets \'h&lm si-ne-'mo-rets\) is the second most prominent (after Hesperides Hill) in the chain of hills surmounting Bulgarian Beach in eastern Livingston Island in the South Shetland Islands, Antarctica.
Sinemorets Hill is 380 m long in east-west direction and 230 m wide, with twin heights, the west-southwestern one being 64 m and the east-northeastern one 62 m, sheltering a small pool between them. It is snow free in the summer months and overlooks the Bulgarian base to the southwest. Relics of an old encampment were still discernible at its eastern slope in 1996.
Sinemorets is the name of a village and a cape on the Black Sea coast. The hill was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1994 at the request of the Second Bulgarian Antarctic Expedition (1993/94).
