James Luna (February 9, 1950 – March 4, 2018) was a Puyukitchum, Ipai, and Mexican-American performance artist, photographer and multimedia installation artist. His work is best known for challenging the ways in which conventional museum exhibitions depict Native Americans. With recurring themes of multiculturalism, alcoholism, and colonialism, his work was often comedic and theatrical in nature. In 2017 he was awarded a Guggenheim Fellowship.

Luna was born in 1950 in Orange, California. He moved to the La Jolla Indian Reservation in California in 1975. In 1976, he earned a Bachelor of Fine Arts degree at the University of California, Irvine, and in 1983, he earned a Master of Science degree in counseling at San Diego State University. In 2011, he received an honorary doctoral degree from the Institute of American Indian Arts.

Luna was an active community member of the La Jolla Indian reservation. He served as the director of the tribe's education center in 1987, and the community was often a focal point of his photography and writing. He taught art at the University of California, San Diego and spent 25 years as a full-time academic counselor at Palomar College in San Marcos, California.

A self-proclaimed "American Indian Ceremonial Clown", "Culture Warrior," and "Tribal Citizen", Luna's artwork was known for challenging racial categories and exposing outmoded, Eurocentric ways in which museums have displayed Native American Indians as parts of natural history, rather than as living members of contemporary society.

While Luna began his art career as a painter, he soon branched out into performance and installation art, which he did for over three decades. He used objects, references to American popular culture, and his own body in his work. He performed over 58 solo exhibitions starting in 1981 and partook in group exhibitions and projects across the United States and the world. His artistry was often referred to as both disruptive and radical for its stark confrontations with colonialism, violence, sexuality, and identity. Some of his best known pieces are:

In The Artifact Piece (1987) at the San Diego Museum of Man, Luna lay naked except for a loincloth and still in a display case filled with sand and artifacts, such as Luna's favorite music and books, as well as legal papers and labels describing his scars. The work looked like a museum exhibit and was set in a hall dedicated to traditional ethnographic displays. The marks and scars on his body were acquired while drinking, fighting, or in accidents. Critics praised Luna's ability to challenge conventional understandings and displays of the Native American identities and presumptions about his own personhood by putting his own body on display. He performed "The Artifact Piece" in 1990 at The Decade Show in New York City.

In the early 1990s, Luna stood outside of Washington DC's Union Station and performed Take a Picture With a Real Indian. Luna describes the performance by saying:

Standing at a podium wearing an outfit, I announce: "Take a picture with a real Indian. Take a picture here, in Washington, D.C., on this beautiful Monday morning, on this holiday called Columbus Day. America loves to say 'her Indians.' America loves to see us dance for them. America likes our arts and crafts. America likes to name cars and trucks after our tribes. Take a picture with a real Indian. Take a picture here today, on this sunny day here in Washington, D.C." And then I just stand there. Eventually, one person will pose with me. After that they just start lining up. I'll do that for a while until I get mad enough or humiliated enough.
