Daniel Mears Jr. (July 28, 1819 – September 22, 1906) was an American lumberman, Democratic politician, and Wisconsin pioneer.
He was a member of the Wisconsin Senate, representing the vast northwest quadrant of the state during the 1858 and 1859 sessions.
He came west in 1848, first settling at Taylors Falls, Minnesota Territory, where he operated a store for a year.
Mears' eldest son, Charles, also served briefly in the Union Army as a corporal in the same company as his father.
He served a bit longer than his father, but was discharged due to disability in August 1862.
