John MacGregor (24 January 1825 Gravesend – 16 July 1892 Boscombe, Bournemouth), nicknamed Rob Roy after a renowned relative, was an English explorer, travel writer and philanthropist.

He founded the British Royal Canoe Club (RCC) in 1866 becoming its first Captain and also founded American Canoe Association in 1880.
MacGregor worked as a barrister in London, and was an accomplished artist who drew all the illustrations in his travel books.
