Stefan Sagmeister (born August 6, 1962) is an Austrian graphic designer, storyteller, and typographer based in New York City. In 1993, Sagmeister founded his company, Sagmeister Inc., to create designs for the music industry. He has designed album covers for Lou Reed, OK Go, The Rolling Stones, David Byrne, Jay Z, Aerosmith, Talking Heads, Brian Eno and Pat Metheny. From 2011 until 2019 he partnered with Jessica Walsh under the name Sagmeister & Walsh Inc.
 He began his design career at the age of 15 at "Alphorn", an Austrian Youth magazine, which is named after the traditional Alpine musical instrument. Sagmeister studied graphic design at the Hochschule fuer Angewandte Kunst, Vienna, graduating in 1986. He later won a Fulbright scholarship to study at the Pratt Institute in New York, where he received a Master of Fine Arts degree.
 In 1991, worked with Leo Burnett's Hong Kong Design Group. In 1993, he returned to New York to work with Tibor Kalman's M&Co design company.
In 1993, he set up his company Sagmeister Inc in New York. He has since designed branding, graphics, and packaging for clients as diverse as the Rolling Stones, HBO, the Guggenheim Museum and Time Warner.

 Sagmeister became the subject of controversy after his performance of a lewd joke about animal fellatio at the annual web conference Webstock in Wellington, New Zealand, in February 2017, embarrassing a sign language interpreter and upsetting some in the audience. The organizers apologized to the interpreter in person, and to attendees following the incident, and on Twitter. Webstock organizers also followed this apology up with a longer statement on their blog.
The joke, according to Fast Company, involved having a sign language interpreter assigned to his talk "interpret a story about a manatee giving itself a blowjob", with repeated requirements to the interpreter to use gestures to indicate the sex act. 
Sagmeister later apologized through the Sagmeister & Walsh Twitter account, and from his personal Instagram account.
 Sagmeister received a Grammy Award in 2005 in the Best Boxed or Special Limited Edition Package category for art directing Once in a Lifetime box set by Talking Heads. He received a second Grammy Award for his design of the David Byrne and Brian Eno album Everything That Happens Will Happen Today in the Grammy Award for Best Recording Package category on January 31, 2010.
 In 2005, Sagmeister won the National Design Award for Communications from the Cooper-Hewitt National Design Museum. In 2013 Sagmeister was awarded the Golden Medal of Honor of the Republic of Austria.
 In 2018 he was voted  Austrian of the Year by the Austrian newspaper Die Presse.
