Carl Frederick William Muesebeck (24 September 1894 - 13 November 1987) was an American entomologist who specialized in the Hymenoptera.
He worked at the insect identification division of the US Department of Agriculture and was also a research associate at the Smithsonian Institution.
His father who worked as a tailor came from Stettin, Pomerania (the family name has variants that include Meusebach) and his mother was from Angermunde, east of Berlin.
Graduating with an interest in biology and entomology he joined the US department of agriculture in 1916 studying gypsy and brown-tail moths in his early years.
Another influential work was his catalogue of Common names of insects approved by the American association of economic entomologists (1946).
