George Newton Kenworthy FRAIA, also known as G. N. Kenworthy or "Kennie" (1885 – 28 October 1954), was a leading Sydney architect and Fellow of the Royal Australian Institute of Architects best associated for his work in partnership with Henry Eli White and for his building designs (particularly theatres) in the Art Deco, Streamline Moderne, Functionalist and Spanish Mission styles.

First articled to Francis Redfern, Kenworthy worked for several leading architectural firms in England before starting his own practice in 1909 in Southport.

[2] In 1911, Kenworthy moved to Sydney, Australia, taking up a position in the New South Wales Government Architect's Office, where he remained until 1923, having risen to be Architect-in-Chief, Secretary's Department, Theatres and Public Halls Section.

[1] He left White's firm in 1929 to start his own practice at 105 Pitt Street, Sydney, where he stayed until his death, working all manner of works though theatres were most prominent as "a recognised authority on the design and construction of theatres and auditoria generally", including the Cremorne Orpheum, Mudgee Regent, Hurstville Savoy, Bankstown Regent and the Port Macquarie Ritz.

[2][3] At a speech to the Institute of Architects at Science House in 1933, Kenworthy observed that the modern theatre building "should be designed for both stage plays and talking pictures, and entrances and foyers should be spacious, and not cluttered up with soda fountains and confectionery counters.
