Sir Pynsent Chernock, 3rd Baronet (before 1670 – 2 September 1734) was a Tory landowner and Member of Parliament from Bedfordshire.
Chernock's early declaration of his candidacy brought him a number of "plumpers" (voters who voted for only one candidate for the two seats), and while the second Tory candidate, John Harvey, was defeated, Chernock topped the poll and pushed out the Whig Lord Edward Russell, the Duke of Bedford's uncle, who polled slightly lower than his fellow Whig Sir William Gostwick.
He continued to be classed as a Tory, but was not active in Parliament, and stood down at the 1708 election; Lord Edward Russell regained the seat.
The increasing popularity and local organization of the Tories allowed Chernock and Harvey to triumph narrowly over the Whig candidates, John Cater and William Hillersden.
His support for the Tory candidates in Bedford failed to secure them that seat in the 1715 election,[1] and he himself was defeated in Bedfordshire by Hillersden.
