Agnewville also known as Smoketown or Chinntown[1] is an extinct unincorporated community in Prince William County, Virginia, United States.

Agnewville lies to the west of the town of Occoquan at the intersection of Minnieville (formerly Davis Ford) and Telegraph Roads.

The Chinn family, freed by Henny Fielder Roe after the American Civil War, was given enough money to purchase about 500 acres[4] of land in 1889.

[2] The Mount Olive Baptist Church was founded in 1915 on Telegraph Road,[2] with land donated by William Wallace Chinn.

The decline of Agnewville came with the relocation of the main highway from Telegraph Road to the present day U.S. Route 1 through Woodbridge, Virginia.
