Lillian Pitt (born 1944) is a Native American artist from the Columbia River Plateau region of the Pacific Northwest. Her Native American name is Wak’amu (camas root), chosen because it represents a "stubborn plant that won’t let go of the earth", referring to the long periods of time she spent wandering the hills during her childhood. Pitt is primarily known for her sculpting and mixed media artistry, which focuses on 12,000 years of Native American history and tradition of the Columbia River region.
