The Diamondback is the award-winning independent student newspaper of the University of Maryland, College Park. It was founded in 1910 as The Triangle and renamed in 1921 in honor of a local reptile, the Diamondback terrapin (the terrapin became the official school mascot in 1933). Until March 2020, the print edition of the newspaper was published once a week on Monday, with a print circulation of 8,000, down from a high of more than 21,000, and what used to be annual advertising revenues of more than $1 million. It was usually twelve to sixteen pages. The Diamondback now publishes a daily digital-only edition during the school year which can be found at dbknews.com.
The paper's current independent status was originally intended as punishment--the Board of Regents cut off student funding after The Diamondback's actions in 1971, when it ran two pages blank in protest of campus censorship and placed tombstones on its editorial page in protest of the Vietnam War.
The paper's offices are located on the third floor of the South Campus Dining Hall, across from the WMUC-FM radio station and the University of Maryland's Residence Hall Association office. 
The Diamondback is split into four sections:
- News - The news section covers both on- and off-campus news, specifically in the region of College Park, Maryland, but also expands coverage to Annapolis, Maryland, when the state's legislature is in session.
- Opinion - The editorial section contains The Diamondback's editorial, op-eds and letters to the editor, and editorial cartoons.
- Diversions - The entertainment section contains reviews of movies and music, as well as concerts and plays around the College Park region.
- Sports - The sports section covers University of Maryland athletics, including men's basketball and football. This section often has a combination of news and opinion articles.
The Diamondback has received many awards throughout its history for categories including photography, news writing and cartoons, especially from the Society of Professional Journalists.
For the 2012-2013, 2015 and 2016 school years, The Diamondback was named the Best All-Around Daily Student Newspaper in Region 2 of the Society of Professional Journalists.
For the 2010-2011 school year, The Diamondback received a first-place Mark of Excellence award for its region, and saw several of its journalists go on to win individual national awards from the Society of Professional Journalists, including for column writing and sports reporting.
