Yoshio Kojima (小島 よしお, Kojima Yoshio, real name: 小島 義雄, born November 16, 1980) is a Japanese comedian famous for appearing only in a small bathing suit, during both performances and interviews.

Among his well-known catchphrases are Sonna no kankei nee (そんなの関係ねぇ or "that has nothing to do with it", usually as a reaction to an intentional mistake in his routine) and Oppapī (おっぱっぴー), an abbreviation of "Ocean Pacific Peace", (オーシャン・パシフィック・ピース).

All of his catchphrases are typically said followed by a signature dance, which has him hunched over, making a punching motion towards the ground while his hind leg is kneed upward simultaneously.

He studied at Waseda University, earning a degree in Japanese literature.

Kojima's "Sonna no kankei nee" was nominated in the 2007 buzzwords-of-the-year contest (shingo ryukogo taisho (新語・流行語大賞)) in Japan.
