John Newsome Crossley, DPhil, MA (Oxon), (born 1937, Yorkshire England) is a well known British-Australian mathematician and logician who is actively writing in the field of logic in computer science, history of mathematics and medieval history. He is influential in the field of mathematical logic in Australia and South East Asia.

Presently, Crossley is Emeritus Professor of Logic at Monash University, Australia where he has been connected since 1968. Prof. Crossley studied at Oxford University where he received his DPhil and MA (Mathematics) in 1963. His early career was spent at Oxford where he was the first university lecturer in mathematical logic and was a Fellow of All Souls College, Oxford. He is still a Quondam there. He was offered a Readership position and following a lecturing visit to Monash University in 1968, he was elected to a Chair in Pure Mathematics. He accepted this position and till today, Crossley continues to be active in the life and progress of Monash University where he serves through its Faculty of Information Technology.

Prof. Crossley is a committed educator and mentor. Many of Crossley's doctoral students have gone on to be professors themselves and have written many books in the field of mathematics or computing. Some examples of these would be Peter Aczel, Wilfrid Hodges, John Lane Bell and Rod Downey.

Crossley is not a single discipline scholar but has a diverse set of interests that he is equally passionate about. He is not only active in mathematical logic but also active in the field history of mathematics and medieval history. He has written books on these disciplines (see books). Aside from being an academician, Crossley is also an avid photographer. In 1974 he first exhibited his photographs in Melbourne and again 2005 he exhibited Composition and Context, a collection of photographs shot by Crossley around the world that illustrates the title and theme of the exhibition. A number of these photographs since have appeared in publications in Australia, Britain and the Philippines.
