Gerald Cassidy (November 10, 1869 – February 12, 1934) was an early 20th-century artist, muralist, and designer who lived in Santa Fe, New Mexico.

[3] At the same moment that Cassidy was first finding success, he contracted a life-threatening case of pneumonia and was moved to a sanitarium in Albuquerque in 1890.

[4] It was here that he first saw the people and places of the American Southwest, the subject matter that he would dedicate his entire life's work to after this point.

[2] He died on February 12, 1934, as a result of turpentine and carbon monoxide poisoning from a newly installed natural gas heater in his studio[10] while working on a mural art project for the dome of the federal building at Santa Fe.

His work is also in Santa Fe at the main post office, Bishop's Lodge, and Hotel La Fonda.
