According to History.com

Ironically, the man with the shortest White House tenure delivered the longest inaugural address in history, which may have been his undoing. This first presidential speech, delivered on a bitterly cold March morning, clocked in at one hour and 45 minutes. Harrison went to bed at the end of inauguration day with a bad cold that soon developed into a fatal case of pneumonia. Some historians have claimed that a case of hepatitis may also have contributed to his demise.

Inaugural addresses aside, are there (other) speeches by a sitting US president longer than that one (1h 45min)?

  • This exactly the speach which is known as the longest one by US president.

    There's an answer that describes a speech given at a CPAC convention. Are you interested in something like that, or only speeches given as part of the presidential duties, like inaugural addresses, State of the Union, televised/radio addresses to the nation?

    Almost surely longer than the longest speech by a standing U.S. President. ;)

  • @Barmar: well, we already have an answer on non-official-capacity speeches. If Harrison's speech is the longest in an official capacity, that would also be interesting to know. Aug 11, 2022 at 7:19

President Trump gave a speech to the 2019 Conservative Party Action Committee (CPAC) which lasted 2 hours and 2 minutes - you can watch the whole thing in its entirety on C-SPAN, if you’re having a slow day. According to the transcript, it contains 16,244 words; almost twice the length of Harrison's speech.

He admitted that he was “completely off script” during the speech, but also argued pithily that “if we don’t go off script, our country’s in big trouble, folks, because we have to get it back.”
