Artist Rooms is a touring collection of international modern and contemporary art in the United Kingdom, established through the d'Offay donation in 2008. Comprising over 1,500 works by 42 artists, it is owned by National Galleries Scotland and Tate which care for the collection together and arrange for its presentation throughout the UK in museums, galleries, and exhibition spaces. Each "room" is devoted to a specific artist with the aim of providing an immersive and comprehensive experience of that artist's work, a format described by Nicholas Serota, former director of Tate Modern, as being "without precedent anywhere in the world."
