Oćestovo Monastery, Serbian Orthodox monastery in Knin, Croatia

Oćestovo Monastery is a monastic complex near Knin featuring a church with traditional Byzantine architectural elements. The site includes buildings for monastic living arranged around the central place of worship, set within the surrounding landscape.

Construction of the Church of Saint Nedjelja began in 1928, because the Orthodox residents of Oćestovo wanted a church at the birthplace of Dalmatian bishop Stefan Knežević. It served the Pađene parish until its consecration in 1960, when it became an independent parish church. On 13 July 2005 Bishop Fotije declared it a monastery, and on 17 July 2005 he served the liturgy there as it became the sixth monastery and first nunnery of the Dalmatian Eparchy.

The monastery serves as a gathering place for the Orthodox community of the region, especially during religious celebrations. The way of life here reflects the traditions and practices of the Serbian Orthodox Church.

The monastery lies in Oćestovo, about ten kilometres west of Knin in northern Dalmatia. The annual assembly is held on the first Sunday after Petrovdan, when pilgrims gather at the church. The current superior is the hieromonk Kirijak (Vranješević).

When it was established, the site became one of the few Orthodox nunneries in the region. This focus on female monastic life gave it a particular role within the broader church structures.
