Ryttmästare (from the German word Rittmeister) was a military rank in the Swedish cavalry in the Swedish Army.

[1] The name was then used for the commander of a company of riders (several of them were usually part of a squadron).

[2] Since the 17th century it was the title for a company officer of the highest rank in the Swedish cavalry with position between lieutenant and major (corresponding to the rank of captain in other branches).

[3][4] A 1967 inquiry (Tjänsteställningsutredningen 1967) considered that the position of ryttmästare as a designation for the rank of captain in the cavalry should be retained as long as the cavalry remained as a service branch in the organization.

[1] The rank was abolished after a reform in 1972 (Tjänsteställningsreformen 1972).
