Joshua David "Josh" Portman (born October 26, 1979) is an American musician who is best known for playing bass guitar for the rock band Yellowcard since February 2012.
After Yellowcard went on "indefinite hiatus" in 2008, Josh Portman left his residence in Atlanta to finish his degree in business at Macon State College.
Wanting to still continue pursuing music and performing, he put together an '80s hair metal tribute band called Great White Lion Snake at the end of 2008.
On September 14, 2009, Ryan Key and Sean O'Donnell made a MySpace blog post that Portman will be playing lead guitar in their side-project, Big If.
After Sean O'Donnell left Yellowcard, Portman returned and was announced as the new permanent bassist on February 17, 2012 and he has been with the band since, including through their hiatus from 2017 until 2022.
