Millfield is a town in the City of Cessnock municipality of New South Wales.

[1] Millfield contains a general store and the historic Rising Sun Inn, which now operates as a museum.

[8] It was flagged for potential closure and sale in June 2018 as part of a diocese plan to raise funds for redress of survivors of child sexual abuse, with services to be consolidated with St John's Church in Cessnock.

[11] Millfield Cemetery, located in Hayes Road, is managed by the Cessnock City Council.

The development was controversial: the original plan for 700 houses did not go ahead, and 500 residents signed a petition against the revised plan on the grounds of overdevelopment of the historic village; however, the rezoning was approved in 2014, with a subsequent council rescission motion lost by one vote.
