John Rogerson (22 October 1741 – 21 December 1823) was a Scottish physician at the court of Catherine the Great of Russia.

He had a distant relative, James Mounsey, who had a position as physician in the court of Peter the Great.

Mounsey returned to Scotland in 1762 and encouraged John to follow a similar, lucrative career.

[2] He also acted in a diplomatic role as advisor to the court,[3] being named a secret councillor by Paul I of Russia in 1796.

He died on 21 December 1823, aged 82, at Dumcrieff House near Moffat in Dumfries and Galloway, less than five miles from his birthplace.
