New Brighton (Welsh: New Brighton; sometimes unofficially Pentre Cythraul, 'devil's village') is a small village in Flintshire, in north-east Wales. It lies between the towns of Mold and Buckley, in the community of Argoed.

New Brighton lies on the A5119 road and has a hotel, the Beaufort Park Hotel.

A New Brighton electoral ward exists, formed from the northern half of the Argoed community, with a total population taken at the 2011 census of 3,001. It forms part of an "Argoed and New Brighton" (Welsh: Argoed a New Brighton) council electoral ward.

Some residents refer to it by its Welsh name Pentre Cythraul, though the Welsh name was not recognised by the Welsh Language Commissioner in 2018, causing local people to ask for this to be reviewed. Pentre Cythraul translates to "the devil's village", although said to have been possibly derived from Pentre Catherall, named after industrialist Josiah Catherall who built some of the village's rows of houses. In their list of standardised Welsh place-names in Flintshire as of November 2023, the Commissioner states the recommended name in Welsh, for Flintshire County Council to use, is "New Brighton".
