Phineas Howe Young (also found as Phinehas) (February 16, 1799 – October 10, 1879) was a prominent early convert in the Latter Day Saint movement and was later a Mormon pioneer and a missionary for the Church of Jesus Christ of Latter-day Saints (LDS Church).

[1] In 1830, Young was contacted by Samuel H. Smith, a missionary in the recently established Latter Day Saint movement.

Young undertook a careful study of the book and eventually passed it on to others in his family, including his brothers Brigham, Joseph and John.

On April 15, 1832, Young and his brother John were baptized into the Latter Day Saint Church of Christ.

While not on missions, Young lived with the Latter Day Saints in Kirtland, Ohio and Far West, Missouri.

Phineas Young was among the first Mormon pioneer company to reach the Salt Lake Valley in July 1847.
