Peter Klashorst (born Peter van de Klashorst, pronounced [ˈpeːtər vɑn də ˈklɑsɦɔrst]; 11 February 1957 – 11 September 2024) was a Dutch painter, sculptor, and photographer.

Klashorst was based in the Tabakspanden on the Spuistraat in Amsterdam,[1] although he also produced works in cities such as Bangkok, Mombasa, and Phnom Penh.

In 2011 he did one of his last self organised shows at the Tuol Sleng, S21 the former Khmer Rouge prison (Cambodia), in honour of the victims of the Khmer Rouge’s terror and genocide that took place from 1975 to 1979 in Cambodia.

The show got world wide attention (The New York Times and Herald Tribune).
