William Morrissey (born August 16, 1986) is an American professional wrestler. He is signed to All Elite Wrestling (AEW), where he performs under the ring name Big Bill and is one-half of Paid In Full with Bryan Keith. He is a former AEW World Tag Team Champion. He is best known for his tenure in WWE, where he performed under the ring name Big Cass.

In WWE, he first appeared under the name Colin Cassidy and came to prominence for his partnership with Enzo Amore, whom he teamed with from 2013 to 2017. Together, they won the NXT Year-End Award for Tag Team of the Year in 2015. He was brought up to Raw alongside Amore the day after WrestleMania 32 and his name was changed to Big Cass. He was later moved to the SmackDown brand, where he had a brief feud with Daniel Bryan, before being released by the company in June 2018. After leaving WWE, he resumed teaming with Amore (now known as nZo) on the independent circuit as Big Cazz, Big C, Big Ca$$, and CaZKL, before joining Impact Wrestling in 2021 as W. Morrissey, and AEW in 2022 as Big Bill.
