Born Richard Johnstone he was the son of Colonel John Johnstone (d. 1741), second son of Sir William Johnstone, 2nd Baronet, of Westerhall. His mother was Charlotte, daughter of John van den Bempde of Hackness Hall in Hackness, near Scarborough, Yorkshire. In 1793 he assumed by Act of Parliament his maternal grandfather's surname of Vanden-Bempde but in 1795 he was authorised by Royal licence to resume the name of Johnstone in addition to those of Vanden-Bempde. Vanden-Bampde-Johnstone was elected to the House of Commons for Weymouth in 1790, a seat he held until 1796. In 1795 he was created a Baronet, of Hackness Hall in the North Riding of the County of York. He died in July 1807, aged 74, and was succeeded in the baronetcy by his son John. His grandson Sir Harcourt Vanden-Bempde-Johnstone, 3rd Baronet, was raised to the peerage as Baron Derwent in 1881.
