Moore grew up in
Ventura County, California, where he played youth ice hockey for the Los Angeles Hockey Club. In high school he played with the
Tri-City Storm, of the
United States Hockey League, in Kearney, Nebraska. He then played three seasons with the
University of Denver. In his freshman year, Moore was named to the
NCHC All-Rookie Team. In his sophomore year, he was named to the
NCAA Second All-American Team and
NCHC Forward of the Year. He subsequently joined the Maple Leafs'
American Hockey League (AHL) affiliate, the
Toronto Marlies, for the
2016–17 season after attending the Leafs training camp. In Moore's second season with the Marlies,
2017–18, he helped them earn their first
Calder Cup. On November 13, 2018, Moore was recalled to the Maple Leafs ahead of their West Coast road trip. He was sent back to the Marlies shortly after, but following an injury to
Tyler Ennis, he was recalled again on December 23. Moore made his NHL debut that night in a 5–4 overtime win against the
Detroit Red Wings, recording up his first career NHL point, an assist on a goal by
Frédérik Gauthier. His first goal was scored four games later, on January 5, 2019, in a 5–0 win over the
Vancouver Canucks. On January 13, Moore signed a two-year contract extension with the Maple Leafs. During the
2019–20 season, on February 5, 2020, Moore (alongside third-round picks in
2020 and
2021) was traded to the
Los Angeles Kings for
Kyle Clifford and
Jack Campbell. On July 24, 2021, Moore signed a two-year, $3.75 million contract extension with the Kings. During the
2021–22 season, Moore achieved career bests in goals, points, and assists. He scored 5 short-handed goals, tying
Alex Formenton for the NHL lead in short-handed goals that year. On March 26, 2022, a petition was launched to rename the roller rink at the Arroyo Vista Community Park in
Moorpark, California to "Trevor Moore's Moorpark Center for More Hockey". On December 15, 2022, the Kings signed Moore to a five-year contract extension with an average annual value of $4.2 million. ==Career statistics==
