Roxie Roker, a star of the long-running CBS television series "The Jeffersons," died on Saturday, her publicity agent said. She was 66.

Her family, including her son, Lenny Kravitz, the rock guitarist and singer, declined to release further details, said the publicity agent, Cynthia Snyder.

Ms. Roker was born in Miami. She grew up in Brooklyn, earned a drama degree from Howard University in Washington and studied at the Shakespeare Institute in Stratford-on-Avon, England. While holding an office job at NBC in New York in the 1960's, she appeared in Off Broadway shows, including Jean Genet's play "The Blacks." In 1967-68, she was a host of "Inside Bedford-Stuyvesant," a community-oriented show on WNEW-TV.

After resigning from NBC and turning full time to acting, Ms. Roker appeared onstage with the Negro Ensemble Company in "Ododo" and "Rosalee Pritchet." She won an Obie Award, and was a 1974 Tony nominee for her performance as Mattie Williams in "The River Niger." Her other Off Broadway credits include "Behold! Cometh the Vanderkellans" (1971) and "Jamimma" (1972).
