The BBC News website picked up the award for general excellence in journalism at the international Online Journalism Awards.
It was the only UK-based site to pick up a prize at the US-based event.
The BBC scooped the prize ahead of the New York Times, Washington Post and Al-Jazeera English.
According to a report on the BBC, the judges praised the website in a posting on Twitter which described it as:
The standard bearer, pushing the whole field forward. Strong in leveraging tech for journalism.
The website's editor Steve Herrmann said:
The award is brilliant news - it comes in the year following a major revamp of the news site, including a complete redesign. It's also been a year of huge news stories and we have been able to be increasingly effective at showcasing all the BBC's newsgathering potential and expertise on the site.
We also launched our North America edition a year ago, and have just announced a further investment in Washington, to run an international edition of our popular Magazine section, with the backing of BBC Worldwide, the BBC's commercial arm, which funds our services internationally.
