Wil Tirion (19 February 1943 – 5 July 2024) was a Dutchuranographer (celestial cartographer). His work, which included star charts and atlases, was widely distributed and renowned by astronomers.^[1][2]

Originally a graphic designer, Tirion became a full-time celestial cartographer after the success of his first star atlas,Sky Atlas 2000.0, published in 1981.^[1] His second major work,Uranometria 2000.0, contained over 280,000 stars and 10,000deep-sky objects across two volumes and was published by Willmann-Bell in 1987.^[1][2] Tirion's sky charts have also been published in astronomy magazines and books, as well as on astronomy websites.^[1]

Tirion's early work was largely done by hand, with computer-generated plots as references. In the mid-1990s, he switched to digital illustration.^[1]

Tirion died on 5 July 2024 at the age of 81 after a brief illness.^[1][2] The asteroid4648 Tirion is named for him.^[2]
