In the early 1950s, Vélez's parents moved from Puerto Rico to Brooklyn, New York, where she and her identical twin sister, Lorraine Vélez, were born. The twins have five other sisters and one brother. Vélez's father, a New York City Police Department officer, eventually bought a house in Far Rockaway, Queens, and moved the family there. The twins staged improvised plays and acting for the family and participated in nearly all their high school drama productions, such as Fiddler on the Roof. After graduating from Beach Channel High School in 1982, they received scholarships to attend the Alvin Ailey Dance School. They went on to study acting at The Acting Studio - New York with its founding artistic director James Price, protégé and personal friend of Sanford Meisner. Lauren also studied Shakespeare with Michael Howard. Vélez landed her first performing job in the national touring company of the musical Dreamgirls.
