The National Institute of Dramatic Art (NIDA) is an Australian educational institution for the performing arts based in Sydney, New South Wales. Founded in 1958, it offers bachelor's, master's and vocational degrees in subjects including acting, writing, directing, scenic construction, technical theatre, voice, costume, props, production design and cultural leadership. In 2024, NIDA was named as #13 in the "World's 25 Best Drama Schools" by The Hollywood Reporter.

NIDA's main campus is based in the Sydney suburb of Kensington, located adjacent to the University of New South Wales (UNSW), and is made up of a range of rehearsal and performance venues. Its performance venues include the Parade Theatre (also the name of an earlier venue in NIDA's history); the Space; the Studio Theatre; and the Playhouse, while the Rodney Seaborn Library forms part of its library and the Reg Grundy Studio is a training and production facility for film and television. Many of Australia's leading actors and directors trained at NIDA, including Cate Blanchett, Toni Collette, Sarah Snook, Mel Gibson, Judy Davis and Baz Luhrmann.
