Villa Lysoen is a historic villa located in the western outskirts of Bergen, Norway. It was built in the mid-19th century as a summer residence for Norwegian violin virtuoso Ole Bull. The villa is situated on the island of Lysoen, which is connected to the mainland by a bridge.

The villa was designed by Norwegian architect Conrad Fredrik von der Lippe in collaboration with Ole Bull, and features a mix of architectural styles, including Swiss chalet, Moorish and Viking influences. The interior of the villa is richly decorated with colorful murals, intricate wood carvings and ornate furnishings, much of which was collected by Bull on his travels around the world.

In addition to the villa, the estate includes a park with exotic trees and plants, several smaller buildings and a concert hall, which was built in 1898 and is still used for concerts and events today. The villa and park are open to visitors during the summer months, and guided tours of the villa are available.

Villa Lysoen is considered one of Norway's most important cultural heritage sites and is an important symbol of Norwegian national identity. It has been designated a national cultural heritage site by the Norwegian government and is protected by law.
