Robert Parry Nisbet JP DL (1793 – 31 May 1882) was a British public man. He was High Sheriff of Wiltshire in 1849, from 1852 a Deputy Lieutenant for the county, and Conservative Member of Parliament for Chippenham from a by-election in 1856 to the 1859 general election. Nisbet's grandson Douglas Robert Hadow (1846–1865) was killed in a mountaineering accident a few hours after taking part in the first ascent of the Matterhorn. Another grandson, Frank Hadow, won the Wimbledon championship in 1878.
