Ludmila (d. October 20 after 1210) was the wife of Mieszko IV Tanglefoot. Her origins are disputed. Mieszko IV Tanglefoot married Ludmila between 1170-1178.

Ludmila contributed to the foundation of the Norbertine monastery in Rybnik, who was later transferred to Czarnowąsy. Mieszko and Ludmila had the following children:
