The suit, filed in Miami federal court, includes one count of defamation and one count of violating a Florida trade practices law. Trump's legal team asked for $US5 billion in damages for each count, for a total of $US10 billion.
Trump accused the UK public broadcaster of defaming him by splicing together parts of a January 6, 2021 speech, including one section where he told supporters to march on the Capitol and another where he said "fight like hell". It omitted a section in which he called for peaceful protest.
The BBC has apologised to Trump, admitted an error of judgment and acknowledged that the edit gave the mistaken impression that he had made a direct call for violent action. But it has said there is no legal basis to sue.
Trump, in his lawsuit, said the BBC despite its apology "has made no showing of actual remorse for its wrongdoing nor meaningful institutional changes to prevent future journalistic abuses."
The BBC is funded through a mandatory licence fee on all TV viewers, which UK lawyers say could make any payout to Trump politically fraught.
A spokesman for Trump's legal team said the BBC "has a long pattern of deceiving its audience in coverage of President Trump, all in service of its own leftist political agenda."
A BBC spokesperson told Reuters earlier on Monday that it had "no further contact from President Trump's lawyers at this point. Our position remains the same."
The UK broadcaster did not immediately respond to a request for comment after the lawsuit was filed.
Facing one of the biggest crises in its 103-year history, the BBC has said it has no plans to rebroadcast the documentary on any of its platforms.
The dispute over the clip, featured on the BBC's Panorama documentary show shortly before the 2024 presidential election, sparked a public relations crisis for the broadcaster, leading to the resignations of its two most senior officials.
Trump's lawyers say the BBC caused him overwhelming reputational and financial harm.
The documentary drew scrutiny after the leak of a BBC memo by an external standards adviser that raised concerns about how it was edited, part of a wider investigation of political bias at the publicly funded broadcaster.
The documentary was not broadcast in the United States.
Trump may have sued in the United States because defamation claims in Britain must be brought within a year of publication, a window that has closed for the Panorama episode.
To overcome the US Constitution's legal protections for free speech and the press, Trump will need to prove not only that the edit was false and defamatory but also that the BBC knowingly misled viewers or acted recklessly.
The broadcaster could argue the documentary was substantially true and its editing decisions did not create a false impression, legal experts said. It could also claim the program did not damage Trump's reputation.
Other media have settled with Trump, including CBS and ABC when Trump sued them following his comeback win in the November 2024 election.
The attack on the US Capitol in January 2021 was aimed at blocking Congress from certifying Joe Biden's presidential win over Trump in the 2020 US election.
