'Dilbert' Creator Scott Adams Dead at 68

8:59 AM PT -- President Donald Trump has just paid tribute to Scott Adams ... sharing a photo of them together in the Oval Office.

POTUS referred to the late cartoonist as a "fantastic guy" who supported him when it wasn't popular to do so. President Trump offers his condolences to Scott's family.

Cartoonist Scott Adams has died after a battle with prostate cancer.

Adams' first ex-wife, Shelly, revealed the news during a live stream on "Real Coffee with Scott Adams" ... reading Scott's final message to his fans.

The letter -- dated January 1, 2026 -- reveals he's still of sound mind ... and that he's converting to Christianity because of the "risk-reward" calculation.

Shelly couldn't bring herself to read the whole letter during the stream ... but, it appears the family released it on X later in the day.

We broke the story ... Shelly told us just yesterday that Scott entered hospice earlier this month and was receiving end-of-life care amid his rapidly declining health. She said nurses were going in and out of the home while she, her daughter, and her sister were providing care as well.

Scott even recorded a podcast episode during which he acknowledged it may be his last ever ... which feels even more poignant now given his passing.

Adams announced he had prostate cancer last year, which had spread to his bones and paralyzed him below the waist.

In the late 1980s -- while working at the Pacific Bell Telephone Company -- Adams launched the "Dilbert" comic strip with United Media.

He became a full-time cartoonist after "Dilbert" was picked up by several hundred newspapers ... and, at its height, the strip appeared in 2,000 of them across the country.

Newspapers began to drop the comic strip in 2023 after Adams advised white people to "get the f*** away" from Black people in a controversial podcast episode. Scott posited his commentary on "wokeness" was why the comic strip was cut.
