Dagmar Olrik (1860–1932) was a Danish painter and tapestry artist.
She is remembered for her weaving and tapestry work, in particular for decorating a room in Copenhagen's City Hall with tapestries based on cartoons of Nordic mythology created by Lorenz Frølich.
For 18 years, she headed a group of tapestry artists in the City Hall's weaving room where the work was completed.
She also restored tapestries for several Danish museums and stately homes.
