John Marino

John Marino (born May 21, 1997) is an American professional ice hockey defenseman for the Utah Hockey Club in the National Hockey League (NHL). He was drafted by the Edmonton Oilers, 154th overall, in the 2015 NHL Entry Draft.

Personal life
Marino was the second of two sons born on May 21, 1997, in Easton, Massachusetts, U.S., to parents Jen and Paul II. Both Marino and his twin brother Paul III weighed over seven pounds, leading doctors to believe one of them would be born with a condition. After Paul III was born with bowed legs, a doctor at Boston Children's Hospital suggested their parents enroll him in hockey lessons. This was because the stride needed for hockey could allow a natural process for his legs to straighten. Jen and Paul II thus decided to enroll both of their sons in hockey lessons at nearly two years old.

Amateur
Marino played junior hockey with the South Shore Kings in the United States Premier Hockey League before he was selected in the fifth-round, 154th overall, by the Edmonton Oilers in the 2015 NHL Entry Draft. After a single season with the Tri-City Storm in the United States Hockey League (USHL), he committed to a collegiate career with Harvard University of the ECAC.

Marino played college hockey at Harvard from 2016 to 2019. He scored his first collegiate goal on October 28, 2016 against Arizona State. In 2016–17, Marino was named Second Team All-Ivy League.

Pittsburgh Penguins
On July 26, 2019, Marino was acquired by the Pittsburgh Penguins in exchange for a sixth round pick. On August 8, 2019, he left the college ranks as he was signed to a two-year, entry-level contract with the Penguins.

Marino made his NHL debut on October 8, 2019, in Pittsburgh's game against the Winnipeg Jets. He scored his first NHL goal on November 4, 2019 against the Boston Bruins.

Prior to the start of the 2021–22 season, Marino trained with Brian Dumoulin in Boston. Together, they would skate before working out at the home gym in Dumoulin's garage in Charlestown. On January 3, 2021, Marino signed a six-year, $26.4 million contract extension with the Penguins.

New Jersey Devils
On July 16, 2022, Marino was traded by the Penguins to the New Jersey Devils in return for Ty Smith and a 2023 third-round pick.
