Roger Arnebergh (August 17, 1909 – January 25, 2004) was an American attorney and elected official.

He was the son of Targe Arnebergh and Amelia Graagaard, who were of Norwegian and Danish ancestry.

Although he dropped out of high school at the age of fifteen, he received a law degree through extension learning.

Arnebergh won the election for Los Angeles City Attorney in 1953 with support from Ray L. Chesebro, who was retiring.

He was briefly in the limelight in 1991, as part of Citizens for Integrity and Viability in the City Charter, which supported former Police Chief Daryl Gates, and was against changes in the selection, removal and tenure of future police chiefs.
