Nancy Meckler is an American-born director, known for her approach to theatre, specifically her work in the United Kingdom with Shared Experience, where she was a joint artistic director alongside Polly Teale. Educated in the US and England, she has directed for a number of prominent theatres, including the Globe Theatre, the Royal National Theatre, and the Royal Shakespeare Company. She has also directed feature films such as Sister My Sister, and Alive and Kicking/Indian Summer.

Meckler is native to Long Island, New York. It was there that she began to take interest in the arts, though directing was not her original passion; at first she wanted to be an actor. She was initially attracted to theatre because of its ability to expose audiences to new and different worldviews. Meckler attended several academic institutions in the US, beginning with Antioch College for her undergraduate degree, then moving on to study acting at HB Studios. Finally, she obtained a master's degree in Performance Theory and Criticism from NYU. Meckler also spent a year in London training at the London Academy for the Dramatic Arts.

After this, her focus slowly moved to directing; she realized she did not want to be in the spotlight, but still had a strong interest in theatre. Her future directorial pursuits were greatly steered by the New York avant-garde scene of the 1960s; her influences at the time included Jerzy Grotowski, a prominent experimental and avant-garde figure of the era. She moved to London in 1968, a time when many American artists were relocating to the UK, permanently changing the theatre scene in the places they landed.

Once in the UK, Meckler founded the Freehold Theatre Company (1968–72), which, while it did not last long, had a successful and recognized production of the play Antigone. In 1970, Antigone was sent by the British Council to represent the UK at BITEF and the Venice Biennale. The Freehold Theatre Company won the John Whiting Award for New Writing in 1970.

Freehold Theatre Company disbanded after Meckler started her family, but she returned to theatre shortly after, becoming the associate director at Hampstead Theatre. During this time, Meckler struggled with the constraints of directing traditional scripted plays and the structure of British theatre, as her work in the past had been more creative and experimental. In 1984, having outgrown the Hampstead scene, Meckler and her husband, David Aukin, who she had been working with at Hampstead, relocated to Leicester Theatre in London. There, Meckler went on to direct the plays of authors such as Shakespeare and other traditional playwrights, but alongside that, she returned to her more experimental pursuits through freelance directing.

Meckler was the first woman to direct at the Royal National Theatre, with Edward Albee's Who's Afraid of Virginia Woolf? in 1981.

She was the artistic director of Shared Experience Theatre, a fringe theatre company in London, from 1988 to 2011. The company is known for its non-traditional approaches to theatre, namely their tendency to stage well known plays in a way that has not been done before.

Meckler has directed 5 plays at the Royal Shakespeare Company as well as King Lear at Shakespeare's Globe.
