Yuko Ogura (小倉 優子, Ogura Yūko?, born November 1, 1983 in Mobara, Chiba) is a Japanese gravure idol and model who typically aims for the cute, innocent schoolgirl look. In Japan, she is mostly called by her nickname Yūkorin (ゆうこりん?).

Ogura regularly, if not entirely seriously, claims to be one "Princess Apple-Momoka" (りんごももか姫) of the apple-shaped planet Korin (こりん星). This is apparently an in-joke dating back to her middle school days. Having an alternate name was trendy at one point, and one of her friends told her that she looked like a Momoka. She liked the name and still uses it today.

She is known outside of Japan for her song "Onna no Ko / Otoko no Ko" (オンナのコ・オトコのコ: Girls・Boys?) which is the ending theme of the anime School Rumble.

She married Isao Kikuchi on October 10, 2011 in Hawaii
