More than 50 UK channels broadcast the service, as the nation paused to pay a final farewell to Queen Elizabeth II.
The overall audience peaked at 12:25 BST, as her coffin was carried through the streets from Westminster Abbey.
Around 20 million people watched on BBC One at that time, while ITV's audience numbers peaked at 5.3 million.
The overnight figures from ratings body Barb do not include all viewers watching through streaming apps like BBC iPlayer and ITV Player, or those who saw it on big screens outdoors or in cinemas, churches or pubs.
A similar number are thought to have watched England's World Cup victory in 1966, although that occurred before the modern TV ratings system began.
Almost 27.7 million watched Boris Johnson's Prime Ministerial statement on 10 May 2020, when he set out a plan to ease the first Covid lockdown.
And the London 2012 Olympic opening and closing ceremonies each attracted almost 24.5 million viewers.
Monday's royal funeral was shown live across most BBC channels - with a signed version on BBC Two - and all ITV and Sky stations.
Children's channels CBBC and CBeebies stuck with their usual programmes, while Channel 5 broadcast the Emoji Movie and Stuart Little - drawing both criticism and praise from parents online.
Channel 4 chose to broadcast the Queen's coronation from 1953 and other royal documentaries.
Most commercial channels did not air adverts on the day, meaning the increased viewing did not result in a financial benefit.
The BBC's coverage of the funeral and processions through London was anchored by Huw Edwards, with David Dimbleby taking over when the cortege reached Windsor for a later committal service.
