James Hunter Samson (c. 1800–March 26, 1836) was a lawyer and political figure in Upper Canada.
He studied at York (modern Toronto), where he became close friends with Robert Baldwin.
He articled in law with Christopher Alexander Hagerman, was called to the bar in 1823 and set up a practice in Belleville.
In the same year, he was elected to the Legislative Assembly of Upper Canada for Hastings; he was reelected in 1830 and 1834.
With the death of his father in 1832 and his increasing alienation from Baldwin due to their conflicting political views, Samson began drinking heavily and he died in Belleville in 1836.
