The passage was navigated and charted by Captain C.R. Elliott in RRS John Biscoe in January 1979. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in association with Harrison Passage and Maskelyne Passage to the northeast, after Thomas Mudge (1715–94), English horologist who made substantial improvements to marine chronometers.
