Robert Mackintosh (c 1745–1807), known as 'Red Rob' on account of the colour of his hair, was a Scottish composer and violinist, active in Edinburgh at the end of the 18th century.
He was known for his compositions of strathspeys, reels, and jigs, as well as minuets and gavottes.
Mackintosh was born in Tullymet, near Pitlochry, Perthshire, about 1745.
Around 1773, he was living in Skinner's Close, just off Edinburgh's High Street, employed as a music teacher and playing in the orchestra of the Edinburgh Musical Society.
He later went to London where in 1804 he produced his fourth collection of a further 113 pieces.
