Acton (sometimes Welsh: Gwaunyterfyn) is a suburb and community in Wrexham, Wrexham County Borough, Wales. It spans the north-eastern part of Wrexham. The area is largely residential and at its centre, lies Acton Park, the location of the former Acton Hall.

The name 'Acton' is derived from Old English, meaning "oak town", and is one of several placenames in the area with an Old English root. As with the neighbouring township of Stansty, the English name remained in use (often spelled in a cymricized form Actyn) under Welsh administration.

"Acton" is still used in Welsh, although the Welsh Language Commissioner has noted a name Gwaunyterfyn, meaning 'boundary meadow or moor'. It originally derives from an irregularly-shaped parcel of land historically referred to by the names "Acton Moor" and "Gwaun y terfyn" (then translated as 'layland of the boundary / the boundary moor') and which formed the boundary between the townships of Acton and Wrexham Regis. The three fields comprising Gwaun y terfyn, or Acton Moor, had by the late 18th lost their older name and had partly been enclosed by Acton Park.

Madog ap Gruffydd Maelor granted land in this area to the monks of Valle Crucis Abbey in 1202 and the charters of Valle Crucis for 1200 and 1222 mention abbey lands at 'Actun'. A 1289 survey of Wrexham townships includes 'Actone vachan' (Acton Fechan – 103 statute acres) and 'Acton vaur' (Acton Fawr – 953 statute acres). By the late 16th century, much of the township had become part of the 'Acton Park' estate of the Jeffreys family. The family based itself at Acton Hall, which was recorded as having 11 hearths in 1670, making it one of the largest houses in the Wrexham area.

Acton was originally one of the townships of the parish of Wrexham (in 1886, the township was transferred to the new ecclesiastical parish of Rhosddu). Under the civil administration, the civil parish of Acton, based on the old township's boundaries, was part of the Wrexham Rural District, but was abolished in 1935 and parts were transferred to the civil parishes of Bieston and Wrexham Regis. All the latter structures were abolished under the terms of the Local Government Act 1972.

In 1985, a Boundary Commission review led to the creation of four new community areas within Wrexham itself, Acton, Rhosddu, Offa, and Caia Park, each of which would have their own community council.

The community of Acton covers approximately 3.34 square kilometres (1.29 square miles) and comprises the electoral divisions (wards) of Acton (Acton Central & Acton Park), Borras Park, Little Acton, Maesydre and Rhosnesni. The southernmost tip of the community area is on the corner of Chester Street and Charles Street in the city centre, and is bounded by Chester Road to the west, Holt Road to the south-east and the Llanypwll link road (A5156) to the north-east. At the 2001 census, it was the most populous community in the county borough with 12,960 people in 5,412 households.

The area neighbours the communities of Rhosddu to the west, Caia Park to the south, Holt to the east and Gresford to the north.
