Rogoi () is a Byzantine castle in Nea Kerasounta near Preveza, in western Greece. It is located on the site of the ancient city of Bouchetion (Βουχέτιον), which was abandoned in the late 1st century BC. Re-occupied in the 9th century, it became a bishopric and was refortified, playing an important role in the region's history in the 14th and early 15th centuries. It was abandoned again after the Ottoman conquest in 1449.
