The Metropolitanate of Karlovci was a metropolitanate of the Eastern Orthodox Church that existed in the Habsburg monarchy between 1708 and 1848. Between 1708 and 1713, it was known as the Metropolitanate of Krušedol, and between 1713 and 1848, as the Metropolitanate of Karlovci. In 1848, it was elevated to the Patriarchate of Karlovci, which existed until 1920, when it was merged with the Metropolitanate of Belgrade and other Eastern Orthodox jurisdictions in the newly established Kingdom of Serbs, Croats and Slovenes to form the Serbian Orthodox Church.

The Krušedol Monastery is a Serbian Orthodox monastery on the Fruška Gora mountain in the Syrmia region, northern Serbia, in the province of Vojvodina. The monastery is the legacy of the last Serbian despot family of Syrmia - Branković. Dedicated to the Annunciation to the Blessed Virgin Mary, it has been described as the "spiritual beacon" of Fruška Gora and "Second Studenica".
