Harvest Moon: Back to Nature, known in Japan as Bokujō Monogatari Harvest Moon, is a video game in the farm simulation series Story of Seasons, developed and published by Victor Interactive Software. It is the first Harvest Moon game for a non-Nintendo console. Characters from Harvest Moon 64 were transferred to be the characters in this game, although with new lifestyles, personalities, and relatives.

A version featuring a female protagonist, Bokujō Monogatari Harvest Moon for Girl, was released in Japan on December 7, 2000. In 2005, Harvest Moon: Back to Nature was coupled with the girl version and ported as Harvest Moon: Boy & Girl, known in Japan as Bokujō Monogatari: Harvest Moon Boy & Girl, for the PlayStation Portable, although the box art and instructions portrayed it as a new game. In 2008, Marvelous Interactive released Harvest Moon: Back to Nature and Bokujō Monogatari Harvest Moon for Girl for the PlayStation 3 and PlayStation Portable via the PlayStation Network.

This game was remade as the Game Boy Advance games Harvest Moon: Friends of Mineral Town and Harvest Moon: More Friends of Mineral Town, both of which would later get a remake of their own for the Nintendo Switch under the name Story of Seasons: Friends of Mineral Town.
