L. John Nuttall (1834–1905) was a printer, missionary, early civic leader in Provo, Utah, and private secretary for Church of Jesus Christ of Latter-day Saints Presidents John Taylor and Wilford Woodruff. Leonard John Nuttall was born in Liverpool, England in 1834 to William Nuttall and Mary Langhorn. He emigrated to Utah Territory in 1852 after converting to Mormonism, settling in Provo. Here Nuttall became involved in many civic affairs. He served in the militia in Utah County and was first elected to the Provo City Council in 1861. Nuttall served in various positions in Provo, including justice of the peace, alderman, auditor and recorder. From 1864 until 1875 he served as Utah County Clerk and clerk of the county probate court. He served as the secretary of the Provo Co-Operative Mercantile Institution from its inception in 1869. Nuttall was also the first person to operate a printing press in Utah County, doing so in 1870.

Nuttall married Elizabeth Clarkson in 1856, and would later take two additional wives: Catherine Ann Conover and Sophie Elizabeth Taylor, daughter of President John Taylor. With Elizabeth he had seven children, and had six with Sophie.

In the LDS Church, Nuttall served for a few years in the 1860s as a member of the high council of the Utah Stake, which covered all of Utah County at the time.
