In 2015, the Indians were regarded as one of the top teams in the state, led by senior All-State running back, Chris Martin. However, the Indians struggled during the first half of the season, as their record after two weeks stood at 0–2, and after six weeks, their record stood at 3-3. The Indians managed to win their final two regular season games and managed to qualify for the MIAA State Playoffs with a 5-3 regular season record. However, much like the previous season, the Indians rolled through the post season, as they won four straight playoff games against three Top 25 teams to advance to the Division 3 State Championship game for the second year in a row. Once again, the Indians would be facing off against undefeated Melrose in a rematch of last year's state championship game. In one of the best games of the season, Dartmouth managed to hold off Melrose in the final seconds once again, defeating the Red Raiders by a score of 26–21 to secure their second consecutive MIAA Division 3 State Championship. Senior running back Chris Martin was named the Massachusetts Division 3 Player of the Year by numerous publications, and was also selected to the All-State team. Dartmouth finished the 2015 season with an 11-3 overall record.
