Aage Gerhard Skavlan (22 December 1847 – 24 February 1920) was a Norwegian historian.
He was born in Herøy as a son of dean Aage Schavland (1806–1876) and his wife Gerhardine Pauline Bergh (1817–1884).
He spent his early career as a school teacher, but also researched history.
He was given a royal scholarship in 1877 to conduct studies at the University of Copenhagen and Lund University, and in 1878 he published his first book Historiske Billeder fra den nyere Tid i Danmark, Norge og tildels Sverige.
In 1881 he received a parliamentary grant to write a history on Norway in 1814; he released books on this topic in 1882, 1884, 1892 and 1899.
