Sir Frank Walters Kitto, AC, KBE, QC (30 July 1903 – 15 February 1994), Australian judge, was a Justice of the High Court of Australia.

At his swearing in, Kitto remarked: "[Australia's] future will be influenced in no small degree by the quality of the work we do in upholding the rule of law and proving its worth and effectiveness in the development of a nation in whose righteousness must lie its greatness.

"[3]Kitto had a complicated writing style, but his judgments were generally highly regarded for being well founded in legal principle.

[4] Michael Kirby considers that Kitto's judgment in the Communist Party case, delivered less than a year after his appointment to the court, remains one of his finest, primarily because of his unwavering support for the rule of law and for the Constitution.

[5][6][1] In 1927, Kitto married Eleanor May Howard and subsequently they had four daughters, Kathleen, Margaret, Lindsay (Lyn) and Elizabeth (Liz).
