Miranda July (born February 15, 1974) is a performance artist, musician, writer, actress and film director. She currently resides in Los Angeles, California, after having lived for many years in Portland, Oregon. Born Miranda Jennifer Grossinger, she works under the surname of "July," which can be traced to a character from a "girlzine" Miranda created with a high school friend called "Snarla."

Miranda July was born in Barre, Vermont, the daughter of Lindy Hough and Richard Grossinger. Her parents, who taught at Goddard College at the time, are both writers. In 1974 they founded North Atlantic Books, a publisher of alternative health, martial arts, and spiritual titles. Miranda was encouraged to work on her short fiction by author and friend of a friend, Rick Moody.

Miranda grew up in Berkeley, California, where she first began writing plays and staging them at the all-ages club 924 Gilman. She later attended UC Santa Cruz, dropping out in her sophomore year. After leaving college, she moved to Portland, Oregon and took up performance art. Her performances were successful; she has been quoted as saying she has not worked a day job since she was 23 years old.
