The Sophie Prize was an international environment and development prize (USD 100,000) awarded annually from 1998 to 2013. It was established in 1997 by the Norwegian author Jostein Gaarder and his wife Siri Dannevig, and is named after Gaarder's novel Sophie's World. It aimed to recognize individuals or organizations working with the environment and sustainable development. In 2013, representatives announced that the prize would not be awarded any longer due to a lack of funds.
