Jonathan Duncan Inverarity (1812 or 1813 – 28 April 1882, Rosemount, Angus) was a civil servant of the Bombay Presidency.
He studied at the Edinburgh Academy from 1824 to 1826 before going to Addiscombe in 1826 and Haileybury from 1828 to 1830.

Inverarity's 1830 notes of the teachings of Thomas Malthus and his interpretations of Adam Smith's Wealth of Nations have been an important source for the study of Malthus' teachings and ideas.

Martha died in 1871 and he later married Agnes Anne Spottiswoode, daughter of Capten Donald Oenas Mackay. They had five sons and a daughter.
