James Mathew Lynch (January 11, 1867 – July 16, 1930) was an American labor union leader.
Born in Manlius, New York, Lynch began working as a printers' assistant on the Syracuse Evening Herald, becoming a press feeder and then completing an apprenticeship as a compositor.
He also served two terms as president of the Syracuse Central Trades and Labor Assembly.
While in the post, he led a successful campaign for a 48-hour working week, established a pension scheme for members, reformed the apprenticeship scheme, and doubled the union's membership.
The following year, he became editor of the Advocate, a labor movement newspaper based in Syracuse.
