Lauritz Godtfred Rasmussen (11 June 1824 – 24 April 1893) was a Danish zinc and bronze caster.

He established a zinc and bronze foundry in his own name in Copenhagen in 1865 and was appointed royal court caster in 1883.

After eight years as a journeyman in Europe, Rasmussen finally returned to Copenhagen in 1852 where he established a small business as a font caster in his father's basement.

In 1859 the foundry relocated to larger premises at Sankt Annæ Gade 34 in Christianshavn and eight years later to Læssøesgade 14 in Nørrebro.

She was the daughter of vineyard-owner and innkeeper Johann Karl Gottlob Rost (died 1833) and Christiane Friederike Götzin.
