Colcot is a northern district of Barry, Vale of Glamorgan, in the Dyfan ward of South Wales.

Dyfan ward is situated in the north west of Barry and its most northern edge is on the green belt of the town.

Dyfan benefits from a sports centre and Buttrills recreation field and The Barry Hospital is located on Colcot Road.

Most notable crimes are the following; On 20 April 2006, an 18-year-old was left with a "cut eye, head injuries and a broken nose" after being punched and robbed of just a few pence by thugs at a bus stop near Colcot Cemetery.

[11] In April 2007, during the Easter holidays, vandals smashed 17 windows of Colcot Primary School, "trashed classrooms, chopped down trees and littered the playground with dozens of cans and broken beer bottles", prompting then headmaster Ieuan Richards to state, "The scale of the vandalism is just horrifying".

[14] Colcot Community Centre on Keats Way allows residents affected by local crime to liaise with police officers.

[18] After six years of "legal wrangling and negotiations over leases and other matters" and numerous acts of vandalism, in October 2005 the dilapidated flats on the square were finally demolished and a new £250,000 development with a general store, chemist shop, and a take-away was built.
