Cheia Monastery (Romanian: Mănăstirea Cheia) — a Romanian Orthodox complex located on the right bank of Tâmpa Creek, southeast of Cheia village (itself part of Măneciu commune), in Prahova County, Wallachia region, southeastern Romania.

A new wooden church was built in the early 1800s, but it was ravaged by fire 30 years later.

[1] The monastery suffered during World War I, when German troops occupied the grounds and destroyed some of the buildings.

In 1950, the Communist authorities forced the bishop of Oradea, Nicolae Popoviciu [ro] into exile at Cheia Monastery, where he died in 1960.
