The Austin Sun was a biweekly counterculture newspaper that was published in Austin, Texas, between 1974 and 1978.

The publication was similar in nature to Rolling Stone during the latter's formative years. The Austin Sun was instrumental in advancing the careers of many musical artists, including Stevie Ray Vaughan, Joe Ely, Marcia Ball, and Butch Hancock.^{[citation needed]} It also covered the first American performances of Elvis Costello, at the Armadillo World Headquarters; and the Sex Pistols, in San Antonio.

The Austin Sun was notable for being the newspaper that started the careers of many persons who later became well-known in journalism and other media. Core former Sun staff members were involved with the publications LA Weekly and The Austin Chronicle.

The Austin Sun was co-founded by Jeff Nightbyrd (formerly Jeff Shero), who had been the editor of The Rat in New York City and associated with The Rag underground newspaper in Austin. Nightbyrd established the paper with Michael Eakin, a former editor at The Daily Texan, the student newspaper of the University of Texas at Austin. They were later joined by J. David Moriarty as managing editor, and considered to be the only person at the paper with business expertise.

Unlike underground newspapers (and despite being so categorized by the Library of Congress), which published much counterculture social and political commentary by volunteer contributors, the Austin Sun was intended to be a commercially viable enterprise, with formal advertising programs and paid staff positions.

The paper's first issue was published on October 17, 1974.

Despite intentions of commercial viability, most staff members of the Austin Sun needed to have full-time jobs elsewhere to provide for themselves. Jeff Nightbyrd regularly offered employees stock in lieu of salaries, though the stock, being printed paper in relation to a private company, bore no relationship to the actual value of the business.

The Austin Sun published its last issue on June 29, 1978.
