Mr. Osomatsu, known in Japan as Osomatsu-san (おそ松さん^?), is a 2015 comedic television anime series by Pierrot, based on Fujio Akatsuka's 1962 manga series, Osomatsu-kun. Celebrating Akatsuka's eightieth birthday, the series follows the sextuplet Matsuno brothers from the original series as adults, and features more adult-oriented humor compared to the original series. The series aired in Japan between October 2015 and March 2016, with a special episode airing in December 2016. A manga adaptation by Masako Shitaro began serialization in Shueisha's You magazine from January 2016.

The original Osomatsu-kun series followed the Matsuno siblings; Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu, who are all identical sextuplets who cause mischief. Mr. Osomatsu depicts the siblings as being ten years older than their original counterparts (with the action taking place in a contemporary setting). All of the siblings have now grown up into lazy NEETs, with each brother having developed their own distinguishing personality. The series follows the siblings in their everyday (and occasionally made up) lives.

Mr. Osomatsu, produced by Pierrot, aired between October 5, 2015 and March 28, 2016 and was simulcast by Crunchyroll, making it the first piece of Osomatsu-kun media to receive an official English release. For the first twelve episodes, the opening theme is "Hanamaru Pippi wa Yoi Ko dake" (はなまるぴっぴはよいこだけ, The Hanamaru Whistle is Only for Good Kids^?) by AouP while the ending theme is "Six Same Faces ~Kon'ya wa Saikō!!!!!!~ (SIX SAME FACES ～今夜は最高!!!!!!～, Six Same Faces ~Tonight is the Best!!!!!!~^?) by Iyami (Kenichi Suzumura) and the Matsuno brothers (Takahiro Sakurai, Yuichi Nakamura, Hiroshi Kamiya, Jun Fukuyama, Daisuke Ono, and Miyu Irino). For episodes thirteen onwards, the opening theme is "Zenryoku Batankyū" (全力バタンキュー, Hit the Sack At Full Force^?) by AouP while the ending theme is "Six Shame Faces ~~Kon'ya mo Saikō!!!!!!~ (SIX SHAME FACES 〜今夜も最高!!!!!!〜, Six Shame Faces ~Tonight is Also the Best!!!!!!~^?) by Totoko (Aya Endō) and the Matsuno Brothers. The series' first episode, which featured multiple parodies, was removed from streaming sites on November 12, 2015 and is replaced by an original video animation in its home video release. Additionally, the third episode, which features a crude parody of Anpanman, was edited for its BS Japan broadcast and is altered in its home video release. A special episode, produced in collaboration with the Japan Racing Association, aired on December 12, 2016.
