Marden Ash is an urban settlement in the Ongar civil parish of the Epping Forest District of Essex, England.

Occupations at the time included two beer retailers, a brewer & maltster company, and a solicitor and clerk to the magistrates.

In the village in 1894 lived two High Ongar JPs, the parish priest, and the minister for the Congregational church.

Also resident was the collector to the guardians & relieving & vaccination officer for the Ongar Union—poor relief provision set up under the Poor Law Amendment Act 1834.

The original church was destroyed during the Second World War in 1945 by a V-2 rocket, and was rebuilt in 1957 in stock bricks with a pantile roof to the designs of Essex architect Laurence King (1907-1981).
