Newport High School (Welsh: Ysgol Uwchradd Casnewydd) is a co-educational secondary school in the Bettws district of the city of Newport, South Wales, UK for pupils aged 11–18 years.

There are about 1,100 pupils from a catchment area to the north western side of Newport.

Following the implementation of comprehensive education the school(s) eventually moved from Queen's Hill to Bettws Lane.

The latter's school plot was sold to Barratt Homes for demolition and house building.
