John Richard Pyke (born 28 August 1940) is an Australian physicist and a former university law lecturer.
Pyke's main interests lie in the fields of legal reasoning and constitutional law.
Pyke has been a consultant to the now-defunct Electoral and Administrative Review Commission and to the independent member for Nicklin, Peter Wellington, on constitutional matters, and has made several submissions to Parliamentary Committees and to the Queensland Constitutional Review Commission.
[9] In 2001 Pyke ran for election to the Senate on a Queensland ticket for Republican Party of Australia.
At the 2010 Federal election Pyke campaigned for governments to impose stricter limits on the numbers of poker machines allowed per State and for limits on the feed rate and to keep up the pressure on all governments to adopt the Productivity Commission's recommendations, and progressively do more to reduce governments' dependence on gambling taxes.
