Martone-Mejail Field - Merrimack's main outdoor stadium - is home to the football, men's and women's soccer, field hockey and men's and women's lacrosse teams.

Martone-Mejail Field received a $1.2 million renovation in the summer of 2005 and the installation of a FieldTurf surface highlighted the upgrade. In addition, the facility was equipped with stadium lighting which allowed teams to play and practice in the nighttime beginning in the fall of 2005.

Several Northeast-10 Conference and NCAA post-season contests have been hosted at this facility, which has a capacity of over 3,000. A press box is located at the top of the grandstand and includes electricity, phone lines, and a public address system. The field includes spacious bench areas for both teams as well as auxiliary practice areas.

Martone-Mejail Field annually has served host to a number of postseason championships. In 2013-14, the field hockey and men's and women's soccer teams hosted at least one round of the NE-10 Championships in the fall, and the men's lacrosse team hosted a First Round matchup in the spring. The field hockey team also hosted the NE-10 Championship Final Four and the NCAA Tournament First Round in 2012. The football team has hosted an NE-10 Championship Weekend playoff game in both 2012 and 2013.

Seating sections surround the entire venue, highlighted with the grandstand on the east sideline that features chair-back seats. Auxiliary sets of bleachers are located on the west sideline as well as at both ends of the field.
