Ezra Thayre (also spelled Thayer) (October 14, 1791 – September 6, 1862) was an early convert and leader in the Latter Day Saint movement.

Thayre was an early convert to the Church of Jesus Christ of Latter-day Saints, being baptized by Parley P. Pratt on October 10, 1830 after he heard Joseph and Hyrum Smith speak about the Book of Mormon.

[4]Shortly after Thayre's baptism, Smith received a revelation that directed Thayre and Northrop Sweet to "open ye your ears and hearken to the voice of the Lord your God, whose word is quick and powerful, sharper than a two-edged sword, to the dividing asunder of the joints and marrow, soul and spirit; and is a discerner of the thoughts and intents of the heart ".

In 1834, Thayre joined Zion's Camp, a group of Latter Day Saints that traveled from Ohio to assist some members of the church in Missouri.

After the death of Joseph Smith in June 1844, Thayre was part of the minority of Latter Day Saints who refused to follow the leadership of Brigham Young and the Quorum of the Twelve.

Affiliated briefly with James J. Strang at Voree, Walworth Co., Wisconsin,[8] but soon returned to New York where he was rebaptized into the LDS Church in September 1854.

[9] He became a member of the Reorganized Church of Jesus Christ of Latter Day Saints in at Galien, Berrien Co., Michigan on August 24, 1860.

[citation needed] The Joseph Smith Papers Project, citing a record of Ontwa Township cemeteries,[10] gives Thayre's death date as September 6, 1862.
