Shimna Integrated College is an integrated secondary school based in Newcastle, County Down, Northern Ireland. The all-ability school was founded in 1994 with the hope of integrating young people from both sides of Northern Ireland's religious divide and giving all of its students 'self-esteem'.

Integrated Education is a Northern Ireland phenomenon, where traditionally schools were segregated, either run as Catholic schools or Protestant schools. On parental request, a school could apply to 'transition' to become Grant Maintained offering 30% of the school places to students from the minority community. Lagan College was the first integrated school to open in 1981.

It opened in September 1994 with 60 pupils. In March 2011, Shimna became the first school in Northern Ireland to organize a gay-straight alliance.

The original buildings are in the process of being replaced with a £16.5m three storey building that meets 2021 design requirements. The plans were approved at the planning committee meeting in April 2021 with completion predicted for September 2023.
