Port O'Brien was an American musical group combining elements of acoustic, folk and indie rock.

They were named after a bay in Alaska featuring a now-abandoned cannery on Kodiak Island where founder member Van Pierszalowski's parents met.

After Cambria moved closer to Oakland they added a rhythm section composed of Caleb Nichols and Joshua Barnhart.

Joshua Barnhart was replaced by Two Gallants drummer Tyson Vogel before the completion of the last studio-recorded album "Threadbare."

"I Woke Up Today" from the album All We Could Do Was Sing was recently used as the backing music for several Dulux Paints television advertisement in Australia.
