Ludvig Nessa (born 11 December 1949) is a Norwegian Lutheran priest who has been noted as a fierce opponent against legalised abortion in Norway since the 1980s, staging various anti-abortion protests and other controversial stunts.
Nessa was defrocked from the Church of Norway in 1989, confirmed after an appeal in 1991, which led him to co-found the independent Deanery of Strandebarm (also known as the "Church of Norway in Exile") together with fellow priests Børre Knudsen and Per Kørner.
Church services administered by Nessa has been broadcast on Visjon Norge since 2014.
