No Fun Mondays (stylized in all caps) is a compilation album of cover songs by Green Day frontman Billie Joe Armstrong, released on November 27, 2020.

The next week, a cover of "You Can't Put Your Arms Around a Memory" was released and, a week after that, a cover of "Manic Monday" featuring a video appearance from Susanna Hoffs.

[5] According to the review aggregator Metacritic, No Fun Mondays received "generally favorable reviews" based on a weighted average score of 68 out of 100 from 7 critic scores.

[11] Stephen Thomas Erlewine of AllMusic calls the album "a bit of a lark, unexpected in its energy but not its contents.

"[9] At NME, editor Andrew Trendell says "Armstrong paints a pretty spot-on portrait of what it’s like to be alive in 2020, told through the hidden gems of his record collection and delivered with the heart and energy that you’ve always known him for.
