Dara Greig is an American professional hockey forward who began her PWHL career with the Montréal Victoire after being selected by the club 23rd overall in the fourth round of the 2024 PWHL Draft. She made her PWHL debut during the 2024–25 season and appeared in 29 games, recording three points (0 goals, 3 assists). Greig returned to Montréal for the 2025–26 season, where she produced a career-best five points, including three goals and two assists, in 29 regular-season games.

The 2025–26 season was particularly significant for Greig as Montréal captured its first PWHL Walter Cup championship. Greig played in all nine of Montréal's postseason games and recorded her first career PWHL playoff point with an assist in the Walter Cup championship-clinching game against the Ottawa Charge. Her two seasons with Montréal totaled 58 regular-season games and eight points (3 goals, 5 assists), in addition to her first playoff point.

Before joining the PWHL, Greig played five seasons of NCAA hockey, spending her first two seasons at the University of Wisconsin, where she was part of the Badgers team that won the 2021 NCAA national championship, before transferring to Colgate University for three seasons. Following Montréal's championship season, Greig returned to the Ottawa area, signing a two-year PWHL contract with the Ottawa Charge through the 2027–28 season on June 20, 2026. She is also the sister of Ottawa Senators forward Ridly Greig.
