Rasmus Morten Andersen (25 September 1861 – 28 February 1930) was a Danish sculptor. He is mainly known for his naturalistic portraits.
Rasmus Andersen was born at Ørting near Horsens where he later trained as a wood carver. He attended the Royal Danish Academy of Fine Arts from 1877 to 1884 and trained to become a sculptor at Wilhelm Bissen's studio. He worked as a conservator at the Art Academy's cast collection until 1905 and at Thorvaldsens Museum from 1893 until his death.
