Ludvig Müller (29 February 1868 – 1 October 1922) was a Norwegian actor and theatre director.

Although he started in his hometown Bergen as a local businessman in 1884 having his own business in operation from 1892, Ludvig made his stage debut at Christiania Theater in 1897 where he stayed for two years before moving on to his thirteen years at the newly established Nationaltheatret in 1899.

[2] From 1913 to 1916 he was theatre director at Trondhjems nationale Scene in Trondheim, a city much farther north.

He died at the German spa town Bad Nauheim in 1922, after having finished a manuscript for Den nye lensmannen, a silent movie released in 1926, four years after his death.

Their son John Grieg Müller (1898–1938) wrote plays, whereas their daughter Else Ulrikke Ludvigsdatter Grieg Müller (1900–76) became an actress and was married in 1933 to Erik Kristen-Johanssen (1901–76), business director and theatre director at Nationaltheatret.
