Honor Molloy (born May 25, 1961) also known as Honour Kane, is an Irish-American playwright. Known for her “signature acrobatic language” and “kaleidoscopic use of malapropisms,” Molloy’s plays and musicals have been produced at over 100 venues across the United States, Canada, England, Ireland, Australia, and India.

Throughout her career, Molloy has been awarded a Pew Fellowship in the Arts, a Harvard Radcliffe Fellowship, a National Endowment for the Arts Creative Writing Fellowship, 3 NYSCA/NYFA Artist Fellowships, 2 Frederick Loewe Awards for Musical Theatre, and a Creative Capital Award. In 2017 she received a Proclamation from the New York City Council for "Contributions to Irish Culture."

Andy Webster of The New York Times has compared Molloy’s writing favorably to that of Conor McPherson and Martin McDonagh. Stanley Crouch of the New York Daily News once described Molloy as “beyond recommendation, her writing and performances should be mandatory events for all civilized people.”

Molloy was born in Dublin, Ireland, where she developed an early love for theatre. Her father, John Molloy, was an actor and playwright at the Abbey Theatre, and her mother Yvonne Molloy was a writer and director for RTÉ and BBC Radio. In a 2017 interview with the Irish Repertory Theatre, Molloy recalled that,

"In the 1950s and 60s, my mother and father worked together in Dublin theaters – from Madame Cogley's Pocket Theatre to The Pike, to The Gaiety, to The Gate. I was in and out of those theaters since I could walk. Actors and producers, writers and musicians dropped by our house when they were in the neighborhood. There was no separation between theatre and life. My big sister Shivaun told me stories – many of them Irish myths. So when I come up with the notion for a new play that's set in Ireland – immediately there are ghosts, and mystery, and shifting theatrical worlds."

As a child, Molloy appeared as Noeleen Feeney, the daughter of her father's character Oliver Feeney, on the RTÉ drama serial Tolka Row. Set in a fictional housing estate on the northside of Dublin, the drama ran for five series from 1964 to 1968.

Molloy later immigrated to Pennsylvania with her mother, spending her adolescence in Greater Philadelphia. She attended NYU's Tisch School of the Arts, where she obtained a BFA in Drama. She later attended Brown University, where she studied under the playwright Paula Vogel and received an MFA in Creative Writing.

From 1990 to 1994, Molloy authored libretto for numerous dance pieces by Susan Hefner & Dancers, including Attempted Flight at Judson Memorial Church, Marrow Clamor at One Dream Theater TriBeCa, Eve of Consumption at Theatre Row, and Unruly Graces at Dia Chelsea. In a 1993 interview with The Morning Call, Molloy discussed authoring the libretto for the later piece while in residency at Millay Arts and Smith College. Unruly Graces consists of 11 scenes, composed of dance and verse. Jennifer Dunning, in a review for The New York Times noted,
