Lear is a 1971 three-act play by the British dramatist Edward Bond. It is a rewrite of William Shakespeare's King Lear. The play was first produced at the Royal Court Theatre in 1971, featuring Harry Andrews in the title role. It was revived by the Royal Shakespeare Company in 1982 with Bob Peck, and revived again at the Crucible Theatre, Sheffield, in 2005 with Ian McDiarmid.

Bond, a socialist, was attempting to reverse modern trends which focused on the Shakespeare play as an artistic experience, at the expense of more practical elements of social critique. By creating a politically effective piece from a similar story, he was more likely to cause people to question their society and themselves, rather than simply to have an uplifting aesthetic experience. According to one critic, his plays "are not meant merely to entertain but to help to bring about change in society". Also, according to Hilde Klein, "Bond argues that Shakespeare gave an answer to the problems of his particular society, which is not valid for our age."

In Bond's play, Lear is a paranoid autocrat, building a wall to keep out imagined "enemies". His daughters Bodice and Fontanelle rebel against him, causing a bloody war. Lear becomes their prisoner and goes on a journey of self-revelation. He is blinded and haunted by the ghost of a Gravedigger's Boy, whose kindness towards the old King led to his murder. Eventually Lear, after becoming a prophet, makes a gesture toward dismantling the wall he began. This gesture leads to his death, which offers hope as an example of practical activism.

The play also features a character called Cordelia, wife of the murdered Gravedigger's Boy who becomes a Stalinist-type dictator herself.

Lear features some punishing scenes of violence, including knitting needles being plunged into a character's eardrum, a bloody on-stage autopsy and a machine which sucks out Lear's eyeballs. The play's emphasis on violence and brutality was mentioned in mixed reviews by top critics. Although some critics praised its message against violence (and its cast), others questioned whether the play was convincing enough to garner the reaction it sought from the audience.

The English Stage Company presented the play at the Royal Court Theatre, where it opened on 29 September 1971, directed by William Gaskill. The cast was as follows:

Sets designed by John Napier
Costumes designed by Deirdre Clancy
Lighting by Andy Phillips

In the late 1970s, the British theatrical community was interested in the failure of the postwar socialist promise, and used historical drama to offer, in the words of Keith Peacock, "a clear reflection of the aspirations, activities, and worries of the Left during the 1970s". According to Louise Geddes, Bond's Lear is "often read as part of the renewed interest in the historical epic, and viewed as a nostalgic response to a troubled time."
