The Obie Awards or Off-Broadway Theater Awards are annual awards given since 1956 by The Village Voice newspaper to theater artists and groups involved in off-Broadway and off-off-Broadway productions in New York City. Starting just after the 2014 ceremony, the American Theatre Wing became the joint presenter and administrative manager of the Obie Awards. The Obie Awards are considered off-Broadway's highest honor, similar to the Tony Awards for Broadway productions.
