Hiromi Oshima (大島 浩美, オシマ・ヒロミ, Ōshima Hiromi?, born on January 6, 1980 in Tokyo) is a Japanese model and was the first Japanese born Playboy Playmate in June 2004. At the time of her centerfold, she was residing in Miami Beach, Florida.

In addition to appearing in the June 2004 Playboy centerfold, she has also starred in a number of Playboy videos as well as Playboy Special Editions.

She appeared in the 2005 Playmates at Play at the Playboy Mansion swimsuit calendar as calendar girl of January. The calendar was the inaugural Playmates at Play calendar and it was shot on the grounds of Playboy Mansion in 2004. It was Playboy's first attempt at creating a non-nude swimsuit calendar featuring Playmates similar in style with those from the Sports Illustrated swimsuit issue. While all Playmates appeared in bikinis in the calendar, only she and Karen McDougal were sporting painted-on bikinis.

She has been listed as a Photo Production Coordinator in various issues of Playboy Special Editions.

She appeared in the music video for Nelly's "Shake Ya Tailfeather".
