David Hazzard (May 18, 1781 – July 8, 1864) was an American merchant and politician from Milton, in Sussex County, Delaware.

John Hazzard was said to have helped ferry the Continental Army across the Delaware River the night before the Battle of Trenton in 1776.

On July 4, 1812, with the coming of the War of 1812, Hazzard was appointed an ensign in the Grenadiers attached to Captain Peter T. Wright's First Company of the 8th Regiment of Delaware militia.

All the while Hazzard was running the family mercantile business in Milton, which now included a granary.

Hazzard was a member of the Jeffersonian Democratic-Republican Party, a minority in Delaware, and particularly in Sussex County.

He ran again in 1826, and lost, this time to Federalist candidate, Charles Polk, Jr. With the realignment of parties that occurred following that election, Hazzard became an Adams-Clay supporter, much more in line with the majority in Delaware.

Accordingly, he won the 1829 election for governor, running as a member of Henry Clay's National Republican Party.

This legislation was encouraged by Hazzard and prohibited the entry into the state of additional free African-Americans, possession of guns without special authorization, unsupervised late night meetings, or unlicensed, itinerant African-American preachers.

He was also a member of the 1852 State Constitutional Convention, but resigned protesting the manner in which the delegates were selected.

Hazzard was an active member of the Methodist Church and as such was a lifelong advocate for social reforms such as the elimination of Delaware's antiquated system of imprisonment for debt.
