Catalina Thomás was a 16th-century Spanish mystic and Augustinian nun born in Valldemossa. Coming from a peasant family, she lived at the Son Gallard estate before joining the Augustinian Canonesses in 1552. She became widely recognized for her holiness and the spiritual guidance she provided to others. After her death in Palma in 1574, she was recognized as a saint within the Catholic Church, eventually becoming a patron of Mallorca.
