Holma is a seat farm in Brastad socken, Lysekil Municipality, Sweden, by the shore of Gullmarn fjord. It was established in the 15th century. Since then, a number of Danish, Norwegian and Swedish noble families, depending on which country Bohuslän belonged to at the time, have resided at Holma. Some of these are the Friis, Bagge and Onstad families. The manor's coat of arms is from the Norwegian time and depicts a lindworm.
