Emma Hale Smith Bidamon (July 10, 1804 – April 30, 1879) was the first wife of Joseph Smith and a leader in the early days of the Latter Day Saint movement, both during Joseph's lifetime and afterward as a member of the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church). In 1842, when the Ladies' Relief Society of Nauvoo was formed as a women's service organization, she was elected by its members as the organization's first president.
