The Baillie Gifford Prize for Non-Fiction, formerly the Samuel Johnson Prize, is an annual British book prize for the best non-fiction writing in the English language. It was founded in 1999 following the demise of the NCR Book Award. With its motto "All the best stories are true", the prize covers current affairs, history, politics, science, sport, travel, biography, autobiography and the arts. The competition is open to authors of any nationality whose work is published in the UK in English. The longlist, shortlist and winner is chosen by a panel of independent judges, which changes every year. Formerly named after English author and lexicographer Samuel Johnson, the award was renamed in 2015 after Baillie Gifford, an investment management firm and the primary sponsor. Since 2016, the annual dinner and awards ceremony has been sponsored by the Blavatnik Family Foundation.
