Patrick Clinch (c. 1790 – March 10, 1868) was a farmer, newspaper owner, and political figure in New Brunswick.
He was born in St. George, New Brunswick, the son of Peter Clinch and his wife Lucretia, and was educated there.
He was a justice of the peace, a justice in the Inferior Court of Common Pleas for Charlotte County, and also served as a school inspector for the county.
He ran unsuccessfully for a seat in the assembly in 1827, losing to Joseph N. Clarke; he successfully appealed Clarke's election in 1828, but this decision was reversed in January 1829.
Clinch died at home in St. George at the age of 79.
