Karamatsu Matsuno (松野まつのカラから松まつ Matsuno Karamatsu) is a character in the series Osomatsu-kun. He is one of the sextuplets.

Although his place in the order of the sextuplets was ambiguous and not of importance in early media, he is established as the second-eldest in more recent works, most notably his counterpart in the 2015-2018 spin-off Osomatsu-san.

His name derives from that of the larch tree, known in Japanese as 唐松 (karamatsu).
