Sinanitsa (Bulgarian: Синаница [siˈnanit͡sɐ]) is a marble peak in the northern part of the Pirin Mountains of southwestern Bulgaria.

Sinanitsa is also known as Chukata (Чуката [ˈt͡ʃukɐtɐ]), Varovita Chuka (Варовита чука [vɐroˈvitɐ ˈt͡ʃukɐ]) or The Split Peak (Разцепения връх, Raztsepenia vrah [rɐsˈt͡sɛpɛnijɐ ˈvrɤx]), the latter because of its unusual south face.

[5] The Sinanishko Lake lies in the eponymous cirque to the north-northwest of Sinanitsa, at 2,181 m (7,156 ft).

[1] Sinanitsa's steep eastern face is a popular destination for alpine climbing.

It was first scaled by Andrey Todorov and Vasil Nastev on 12 July 1949; the first winter ascent was accomplished on 27 April 1955 by Encho Petkov and Yordan Machirski.
