The rainbow plaque programme is a UK scheme to create commemorative plaques to highlight significant people, places and moments in LGBTQIA+ history. Emulating established UK blue plaque programmes run by English Heritage, local authorities and other bodies, the first permanent rainbow plaque (a blue circular plaque with six rainbow colours around the circumference) was unveiled in York in July 2018. Some UK LGBT locations are denoted by pink plaques, an idea that predated rainbow plaques.
