Brandon Gormley (born February 18, 1992) is a Canadian professional ice hockey defenceman who is currently playing for the Iserlohn Roosters of the Deutsche Eishockey Liga (DEL).

Gormley left his home in Prince Edward Island at the age of 14 to compete with the Athol Murray College of Notre Dame's hockey program in Wilcox, Saskatchewan.

In 2007–08, he scored 23 goals, and 53 points over 42 games as a 16-year-old, after which the Moncton Wildcats made him the first overall selection in the 2008 Quebec Major Junior Hockey League (QMJHL) Draft.

In the second year of his entry-level contract, Gormley remained with the Pirates, quickly assuming leadership responsibilities to be selected as an Alternate Captain for the 2013–14 season.

[10] Gormley was used heavily in all situations with the Pirates and was placing 8th in the AHL in scoring amongst blueliners, before he received his first NHL recall by Phoenix on March 7, 2014.

[11] Gormley featured in 5 games with the Coyotes going scoreless before he was returned to Portland to finish the season with new career offensive highs all across the board.

Approaching the final year of his rookie contract with the Coyotes, Gormley failed to establish a first-team position and was familiarly reassigned to the Portland Pirates to begin the 2014–15 season.

[12] With the Coyotes languishing in the standings, Gormley was recalled on several occasions throughout the season, and although given opportunity failed to cement a regular position among the defense corps.

[13] Unable to develop as the Coyotes had hoped and with his eligibility to waivers, Gormely was traded by Arizona to the Colorado Avalanche in exchange for the rights to restricted-free agent Stefan Elliott on September 9, 2015.

[14] Gormley made the Avalanche roster to begin the 2015–16 season, making his debut with Colorado in a 1–0 overtime defeat to the Carolina Hurricanes on October 21, 2015.

Gormley contributed with 2 goals and 10 points in 35 games before he was traded by the New Jersey Devils to the Ottawa Senators for future considerations on March 6, 2017.

[22] Following his release from the Marlies, Gormley opted to accept a European offer, signing a one-year deal with Swedish outfit, Mora IK of the SHL, on October 16, 2017.

[26] As a free agent, Gormley opted to continue his tenure in the KHL by agreeing to a one-year contract with HC Sochi on August 15, 2022.
