Ellen G. White, American religious leader and author, co-founded the Seventh-day Adventist Church (died 1915)

Ellen Gould White was an American author, and was both the prophet and a co-founder of the Seventh-day Adventist Church. Along with other Adventist leaders, such as Joseph Bates and her husband James White, she was influential within a small group of early Adventists who formed what became known as the Seventh-day Adventist Church. White is considered a leading figure in American vegetarian history. Smithsonian named her among the "100 Most Significant Americans of All Time".

The Seventh-day Adventist Church (SDA) is an Adventist Protestant Christian denomination which is distinguished by its observance of Saturday, the seventh day of the week in the Christian (Gregorian) and the Hebrew calendar, as the Sabbath, its emphasis on the imminent Second Coming (advent) of Jesus Christ, and its annihilationist soteriology. The denomination grew out of the Millerite movement in the United States during the mid-19th century, and it was formally established in 1863. Among its co-founders was Ellen G. White, whose extensive writings are still held in high regard by the church.
