Robert Hamilton Macintyre TD RIBA ARIAS (2 February 1940 – 18 September 1997) was a Scottish architect with a particular interest in church architecture and in the work of Charles Rennie Mackintosh.

Born 2 February 1940,[1] Glasgow, Scotland, Robert Hamilton Macintyre (Nic) attended the Irvine Royal Academy after his family moved to Kilwinning in Ayrshire.

Macintyre began his career in the Glasgow offices of Keppie, Henderson and Partners, the successors to Charles Rennie Mackintosh's practice.

He then joined Gillespie, Kidd and Coia (1966) where he worked alongside Andy MacMillan and Isi Metzstein on St Margaret's RC Church, Clydebank (1970–72).
