Mušov (German: Muschau) is a cadastral area and a defunct village belonging to the village of Pasohlávky, South Moravia, Czech Republic. It covers an area of 1420.6 ha.
Mušov was the lowest-lying village in the Břeclav District. The village was destroyed despite the opposition of its inhabitants in the late 1970s, due to the decision of the then socialist authorities to build the Nové Mlýny reservoirs by flooding a unique ecosystem of the riparian forest in the area around the river Thaya. In 1976, the village was merged with the neighboring village of Pasohlávky. The residents of Mušov could choose whether they wanted an apartment or to build a house in a newly built street in Pasohlávky. The village was flooded between 1981 and 1987. The post office in Mušov was last opened on 30 June 1978.
Thanks to the efforts of conservationists, it was decided to preserve the medieval St Leonard's church, now standing on a small island in the middle of the Věstonice Reservoir (the middle reservoir). An archaeological survey has found that the church is much older than previously thought. St Leonard's church, originally a late Romanesque building dating from the late 12th century, was rebuilt in Gothic style in the 14th century. The dating of subsequent Baroque modifications is not known. The abandoned island with the church is an important bird nesting spot and a protected area listed in the ecological network Natura 2000. It is opened to public during the summer months.
