David Plant (March 29, 1783 – October 18, 1851[1]) was a United States representative from Connecticut.
Plant practiced law in Stratford and became a judge of the probate court of Fairfield County.
Plant was a member of the Connecticut House of Representatives from 1817 to 1820 and served as its first speaker in 1819 and 1820.
The following year he became Lieutenant Governor of Connecticut, a position he held until 1827.
He did not seek re-election as an Adams man in 1828, but he did receive a small number of votes as a Jacksonian candidate, as he had in the 1825 and 1826 gubernatorial elections.
