Before the arrival of the First Fleet in 1788, the Enfield area belonged to the Wangal people, a clan of the Eora tribe, which covered most of Sydney. In the early years, the Eora people were badly affected by smallpox, which arrived with the British. Many of the clans became unsustainably small and the survivors formed new bands who lived where they could. While it would be wrong to say that the local indigenous population gave no resistance to British land claims (Pemulwuy being a notable example), within thirty years or so of the colony's establishment, most of the land in the inner-west had been conceded to British settlers.

William Faithful was granted 100 acres (40 hectares) in 1810 covering what is now Enfield as well as much of Croydon Park and parts of Burwood and Croydon. In 1812, Liverpool Road was built through Faithful's land and the high position of Enfield made it a sensible spot for a staging post along the road. By the mid-1840s a small village had formed and the surrounding area supported vegetable gardening and a timber industry. St Thomas' Anglican Church was built in 1848 and is the oldest surviving building in the suburb.

In 1853, a post office was built. This was the first recorded use of the name Enfield for the area although it may already have been unofficially known as that. In 1889, Enfield was deemed large enough to have its own municipal council which covered a larger area than the current suburb including those parts of the current Burwood and Strathfield councils south of Liverpool Rd. In 1891, its municipal population of 2,050 was larger than that of neighbouring Strathfield (1,850) and only just smaller than another neighbour Canterbury (2,426). Enfield retained its separate identity until 1949 when the NSW state government decided to abolish a number of small local councils by amalgamating them with their neighbours. Thus Enfield was absorbed into Burwood and Strathfield.
