Constanza Romero (born 1958) is an American artist and theater designer who lives in Seattle, Washington.
Romero's parents divorced in 1969, when she was 11. Her mother found a teaching job in Fresno, California, and moved there with Romero and her younger sister and two younger brothers. In 1972 her mother died of breast cancer, and the four children went to live with a maternal aunt and uncle near Fresno.
Romero met August Wilson in 1990 when her Yale School of Drama teachers assigned her to design costumes for his new play, The Piano Lesson. Wilson and Romero married in 1994. They had a daughter, Azula Carmen Wilson, prior to Wilson's death in October 2005.
