Sinja Gorica (pronounced [ˈsiːnja ɡɔˈɾiːtsa]; German: Schweinbüchl[2] or Schweinsbüchel,[3] later Scheinbüchel[4]) is a settlement immediately northwest of Vrhnika in the Inner Carniola region of Slovenia.

The newer part, the hamlet of Sap, stands along the main road from Vrhnika to Ljubljana.

[6] Sinja Gorica was first mentioned in written sources in 1414 under the German name Sweinpuhel (literally, 'pig hill'), and as Sweinpůhel in 1418, Singa goriza in 1474, and Sweinpuhl in 1496.

A less likely theory is that the German name was a mistranslation of the Slovene adjective sinji 'light blue', referring to pigmentation of the soil.

The local church in the settlement is dedicated to the Prophet Job and belongs to the Parish of Vrhnika.
