Marriner Wood Merrill (25 September 1832 – 6 February 1906) an American pioneer and religious leader.

Merrill left Sackville and worked briefly as a cook on a fishing schooner based in Boston, Massachusetts, before returning on word of his father's fatal fall into a tidal marsh in May 1851.

He migrated to Salt Lake City, Utah Territory, the following year in a wagon company led by William Atkinson, also of Sackville.

[8] The Merrills briefly relocated to Spanish Fork before the arrival of Johnston's Army in the Utah War.

Merrill became the first president of the Logan Temple in 1884 and a member of the Quorum of the Twelve Apostles on 7 October 1889.

[14] Merrill married his eighth wife, Swedish immigrant Hilda Maria Erickson, after the 1890 Manifesto announced the discontinuation of plural marriage.

[15][16] Merrill was summoned twice as a witness before the United States Congress during the Smoot investigation, but declined, citing poor health.
