Lieutenant-Colonel John Pitt Kennedy (1796–1879) was a British military engineer, agricultural reformer and civil servant. Kennedy was born at Carndonagh, County Donegal, Ireland and was educated at Foyle College, Derry, and the Royal Military Academy, Woolwich, becoming lieutenant in the Royal Engineers in 1815. Four years afterwards, he was sent to Malta, and thence to Corfu. He superintended the construction of a canal at Lefkada (1820), served next under Sir Charles Napier at Cephalonia (building lighthouses, roads, and quays) and was sub-inspector of militia in the Ionian Islands (1828–31).
