John Torkel Wallmark (4 June 1919 – 5 February 2007) was a Swedish electrical engineer and researcher in semiconductor electronics and innovation technology.

Torkel Wallmark was born in Stockholm. He graduated from the Royal Institute of Technology in 1944, became technology licentiate in 1947 and technology doctor in 1953. He was then a researcher at Radio Corporation of America in Princeton, US 1953–1964.[https://runeberg.org/warden/1969/1012.html Wallmark, Torkel]{{dead link|date=December 2023|bot=medic}}{{cbignore|bot=medic}} i Projekt Runeberg[https://archive.today/20130418024725/http://www.chalmers.se/sections/om_chalmers/akademiska_hogtidlig/promotion/chalmersmedaljen/torkel-wallmark Chalmers: Torkel Wallmark], read 10 August 2009

In 1964, he returned to Sweden as a professor in solid state electronics at Chalmers University of Technology. (The professorship was initially named electron physics III.) In 1983 he transferred to a personal professorship in innovation technology at Chalmers, which was the first in this subject area in Sweden. Torkel Wallmark's business in innovation technology has contributed to the establishment of seed companies based on research at Swedish technical colleges, especially Chalmers.Nationalencyclopedin band 19 (1996), the reference word Torkel Wallmark
