James Sayers (2 September 1912 – 13 March 1993) was a Northern Irish physicist who played a crucial role in developing centimetric radar, which is now used in microwave ovens.

He obtained an MSc at Queen's University Belfast, then attended St John's College, Cambridge gaining a PhD.

From 1939 to 1943 he conducted research for the Admiralty at the University of Birmingham on centimetric radar, producing the cavity magnetron.
