Heronsgate (or formerly Herringsgate) is a settlement on the outskirts of Chorleywood, Hertfordshire founded by Feargus O'Connor and the Chartist Cooperative Land Company (later the National Land Company) as O'Connorsville or O'Connorville in 1846.

The Chartist Cooperative Land Society was launched by the National Charter Association in 1845 with the aim of resettling industrial workers from the cities on smallholdings, making them independent of factory employers and potentially qualifying them for the vote.^{[citation needed]}

Chartists were invited to subscribe regular amounts towards an eventual £2.50 (£2/10s) share in the venture. Soon the money began to flood in, pennies and shillings at a time, and was deposited in an account held by Feargus O'Connor in the London Joint Stock Bank.^{[citation needed]}

The land was bought on 14 March 1846, the plots allocated by ballot on 20 April 1846 (Easter Monday) and settled on 1 May 1847.^{[citation needed]}

The 35 plots of land^[1] covering 103 acres (0.42 km²), consisted of 17 plots of 2 acres, 5 plots of 3 acres and 13 plots of 4 acres.^[2] A beer house established on the edge of the estate is now known as the Land of Liberty, Peace, and Plenty public house.^[3]

The National Land Company was wound up by Act of Parliament in 1851. The estate was administered by the Court of Chancery until the freeholds were sold off by auction on 27 May 1857.^{[citation needed]}

Heronsgate lies by junction 17 of the M25, to the south of Chorleywood.
