Lomma Municipality (Lomma kommun) is a municipality in Skåne County in southern Sweden, about 10 km north of Malmö. Its seat is located in Lomma with secondary locality Bjärred being of almost equal population size.
The present municipality was created through the amalgamation of the market town Lomma and the rural municipality Flädie. It took place in 1963, between the two nationwide local government reforms of 1952 and 1971.
The small municipality borders to Kävlinge Municipality, Burlöv Municipality, Staffanstorp Municipality and Lund Municipality. As Burlöv also is notably small, Lomma Municipality almost borders to Malmö Municipality too.
It is situated by Öresund, at the inlet of the small river Höje å. Along the river lies a yacht marina. In the old industrial area along the river new appartements and villas are erected, with some facing the river or the beach. The beaches along its coasts also attract visitors from other municipalities; Lomma Municip
