Sir Martin John Taylor, FRS (born 18 February 1952) is a British mathematician and academic.

He was elected Warden of Merton College, Oxford on 5 November 2009, took office on 2 October 2010 and retired in September 2018.

In 1981 he proved the Fröhlich conjecture relating the symmetries of algebraic integers to the behaviour of certain analytic functions called Artin L-functions.

In recent years his research has led him to study various aspects of arithmetic geometry: in particular, he and his collaborators have demonstrated how geometric properties of zeros of integral polynomials in many variables can be determined by the behaviour of associated L-functions.

[7] His hobbies include fly fishing and hill walking,[8] and he is an enthusiastic supporter of Manchester United.
