Almon Whiting Babbitt (9 October 1812 – c. 7 September 1856) was an early leader in the Latter Day Saint movement, a Mormon pioneer, and the first secretary and treasurer of the Territory of Utah. He was killed in a raid by Cheyenne Native Americans in Nebraska Territory while travelling on government business between Utah and Washington, D.C.

Babbitt was born in Cheshire, Massachusetts to Ira and Nancy Babbitt. He graduated from Ohio State University at Cincinnati and became licensed to practice law in six states. He married Julia Ann Johnson on 23 November 1833 and is thought to have joined the Latter Day Saint church sometime in 1833. In 1834, he was a member of Zion's Camp, and on 28 February 1835 he was ordained as one of the first seventies in the church by Joseph Smith, Jr. Babbitt later became a high priest in the church.

In 1837 and 1838, Babbitt was a missionary for the church in Upper Canada. He attempted to move to Missouri in 1838 but was among the Latter Day Saints who were driven out by unfriendly residents, eventually settling in Nauvoo, Illinois. At a conference of the church in May 1839, Babbitt, Robert B. Thompson, and Erastus Snow were appointed to be a traveling committee that was charged with "gather[ing] up and obtain[ing] all the libelous reports and publications which had been circulated against the Church."

In 1841, Babbitt was appointed as the president of the church's Kirtland Stake, where he was charged with shepherding the Latter Day Saints who did not have the financial resources to move to Nauvoo. In 1843, Babbitt's tenure ended in Kirtland and he began actively practicing law in Nauvoo; he was frequently employed to defend Latter Day Saints in legal disputes. While in Nauvoo, Babbitt was also selected by Joseph Smith, Jr. to become a member of two select groups: the Anointed Quorum and Council of Fifty.

In 1844, Babbitt was elected to the Illinois House of Representatives. In February 1846, Babbitt, Joseph L. Heywood and John S. Fullmer were together given charge over the affairs of the church in Nauvoo after the departure of the church apostles. After the Battle of Nauvoo in September 1846, Babbitt and the two other men signed the treaty that "surrendered" the city of Nauvoo's charter.

In 1848, Babbitt emigrated to Utah Territory to join the gathering of the Church of Jesus Christ of Latter-day Saints (LDS Church), led by Brigham Young. In Utah, Babbitt, a Democrat, became involved in politics. In 1849, he was selected by the provisional General Assembly of the State of Deseret to travel to Washington, D.C., and petition for statehood on behalf of the Assembly. Instead, the federal government created the Territory of Utah and in 1853 Babbitt was appointed secretary and treasurer of the territory. In this position, Babbitt had frequent clashes with Brigham Young, the territorial governor and the president of the LDS Church. These clashes have been attributed in part to Babbitt's tendency to view himself as a representative of the United States federal government rather than an enabler of Young's pro-LDS Church policies.

Babbitt led a company of Mormon pioneers to Utah in 1851.

In addition to his clashes with Brigham Young, Babbitt was involved in a number of conflicts with Latter Day Saint leaders from his early days in the church. On 27 December 1833, Babbitt and his wife were summoned before a disciplinary council on an unspecified complaint; however, when the accusers failed to appear at the council, the charges were dismissed. On 19 August 1835, Babbitt brought before the church's high council on charges that included "not keeping the Word of Wisdom." Babbitt admitted the offence of breaking the Word of Wisdom and stated "that he had taken the liberty to break the Word of Wisdom, from the example of President Joseph Smith, Jun., and others, but acknowledged that it was wrong." The council "reproved" him and "instructed him to observe the Word of Wisdom, and commandments of the Lord in all things".
