Anna Elvira Oscaria Rydkvist (1 December 1879 – 10 July 1942) was a Swedish actress and theatre director.

The leading Swedish theatre practitioner Albert Ranft employed Rydkvist in his company, and she began to tour with his troupe.

Axel Engdahl [sv] engaged her to appear at the Folkteatern, and she was cast in several revue performances, farces, and comedies, until 1922.

Her strong point on stage was her soprano voice, and she began to appear not only in light comic roles but also played fully developed characters.

Rydkvist's involvement as the manager served as a crucial milestone in the theatre's successful run, and Lilla teatern's repertoire featured productions on women's rights and conditions.
