The Drama Desk Award for Outstanding Lighting Design of a Musical is an annual award presented by Drama Desk in recognition of achievements in theatre across collective Broadway, off-Broadway and off-off-Broadway productions in New York City.
The award was established in 1975, with the Drama Desk Award for Outstanding Lighting Design being presented each year to any play or musical production. For 2009, the singular award was replaced by separate play and musical categories, but then merged again from 2010 to 2015; the separate play and musical categories have again co-existed since 2016.
