James Jordan Vermilyea (born February 10, 1982) is an American former professional baseball pitcher, and is currently the pitching coach for the Tennessee Smokies.

In three seasons for the Blue Jays minor league system, Vermilyea posted a 19–9 record with eight saves and a 3.05 ERA in 99 games, 22 as a starter.

He made his major league debut on April 22 against the Baltimore Orioles, pitching 3 scoreless innings as a reliever.

He led his team to the first half championship, but on August 28, 2010, his contract was purchased by the Blue Jays, preventing him from participating in the postseason or setting the GBL saves record.

Vermilyea also utilized his ability to throw a low 80's mph breaking slider, a splitter, a curveball, a change-up, and a cutter.
