In the Beginning: The Bible Stories (手塚治虫の旧約聖書物語, Tezuka Osamu no Kyūyaku Seisho Monogatari, lit. Osamu Tezuka's Old Testament Stories) is a Japanese-Italian anime television series based on The Bible's Hebrew Scriptures (Old Testament) created by Osamu Tezuka. The series was a coproduction between Japan's Nippon TV, Tezuka's Tezuka Productions, and Italy's government-owned broadcaster, Radiotelevisione Italiana (RAI). Although the series was in production during a period of several years in the late 1980s and early 1990s, it was not aired in Japan until 1997, on the satellite channel WOWOW, while it premiered in Italy in 1992 on Rai 1. The series has also been aired on TV in the United States (on the Catholic-oriented Eternal Word Television Network), Spain, Germany, and Australia (on Australian Christian Channel).

In the Beginning marked the fourth time Bible stories formed the basis of a Japanese-animated television series, following the two Superbook series and The Flying House, which were made for Pat Robertson's Christian Broadcasting Network by Tatsunoko Production in the early 1980s.

In the Beginning features episodes devoted to most of the major Bible stories of the Old Testament, including the stories of the Creation, Cain and Abel, Noah's Ark, Abraham and Isaac, Joseph, Moses, David, and Solomon, with the final episode featuring the birth of Jesus Christ. As with the second Superbook series, some stories were stretched out over several episodes. Unlike Superbook and The Flying House, however, no contemporary characters from modern times were inserted into the stories, save for the series mascot and viewpoint character, Roco the fox (whose appearances were removed in the United States edit of the English dub).

Tezuka's manga work frequently included religious themes, and because of his long-running manga Buddha, he is sometimes perceived as having been a devout Buddhist, but in fact, Tezuka was largely agnostic.

The theme music (for the American version), an ending theme called "Rainbow Blue", is performed by Reimy.
