Helen Hardin (1943- 1984) was an American painter. She was also known as "Tsa-sah-wee-eh", which means “Little Standing Spruce”. Her parents were Santa Clara Pueblo artist, Pablita Velarde and a Caucasian former police officer and Chief of Public Safety, Herbert Hardin. She started making and selling paintings, participated in University of Arizona’s Southwest Indian Art Project and was featured in Seventeen magazine, all before she was 18 years of age.

As her career matured and she gained confidence, Hardin became known for painting complex works that combined colorful images and symbols from her Native American heritage with modern abstract art techniques. Her work frequently incorporated images of women, chiefs, kachinas and designs from pueblo pottery, and integrated modern elements as her career advanced. For instance, the paintings of kachinas and blanketed chiefs integrated geometric patterns made with drafting templates, rulers and protractors. Kachinas, or heavenly messengers, had special spiritual meaning, similar to the saints from her Catholic tradition, connecting between people on earth and heaven.
