The Holy Mountains Lavra of the Holy Dormition (Ukrainian: Свято-Успенська Святогірська Лавра, Sviatohirsk Lavra or the Sviatohirsk Cave Monastery) is a major Orthodox Christian monastery on the steep right bank of the Siverskyi Donets River. The name comes from the surrounding Holy Mountains; the Holy Dormition is another term for the death of the Virgin Mary.

The monastery is near the town of Sviatohirsk (so named for the monastery in 2003), in Donetsk Oblast, eastern Ukraine. The monastery also forms the centrepiece of the Holy Mountains National Nature Park (established 1997). The Ukrainian Orthodox Church (Moscow Patriarchate) proclaimed it a lavra in 2004.
