Portland has become a hidden gem for minor league sports, with something for every fan. Whether you’re catching a Sea Dogs game at Hadlock Field, watching the Mariners hit the ice, or enjoying the Celtics' high-energy basketball action, there’s always a reason to show up and cheer. With the Portland Hearts of Pine bringing soccer to the mix later this year, the city’s sports scene is only getting better.
Maine Mariners
Minor League Hockey | ECHL
Since their debut in 2018, the Maine Mariners have quickly become a cherished part of Portland’s winter season. An ECHL franchise and an affiliate of the Boston Bruins, the team has revived the city’s rich hockey tradition after the departure of the Portland Pirates and the original Mariners of the 1970s and ’80s AHL fame. The current Mariners bring the same passion and energy to the ice, proudly carrying on the local legacy of great hockey while forging strong ties with the community. Their name and branding celebrate Maine’s maritime heritage and honor the state’s values of resilience and determination.
The team has built a devoted fanbase thanks to their competitive spirit and commitment to giving back. With playoff appearances already under their belt and players making the leap to the NHL, the Mariners have proven themselves to be a vital part of the Bruins’ development pipeline. Whether you’ve been a hockey lover for years or are just discovering the thrill of the game, cheering on the Maine Mariners is supporting a proud piece of Portland’s sports history and a symbol of the city’s enduring love for hockey.

Portland Sea Dogs
Minor League Baseball | MiLB Double-A
For over two decades, the Portland Sea Dogs have been a staple in town, playing at the iconic Hadlock Field—a ballpark known for its friendly atmosphere and its own "Green Monster," a nod to Fenway’s famous wall. The Sea Dogs' affiliation with the Boston Red Sox has led to a strong connection between the two teams, with many future stars spending time in Portland before making their mark in the major leagues. Over the years, the Sea Dogs have seen several notable players pass through, including Red Sox stars like Mookie Betts, Xander Bogaerts, and Rafael Devers.
Catching a Sea Dogs game on a sunny spring day is the perfect family-friendly adventure. The Sea Dogs create a fun and engaging experience with interactive activities, such as fan contests, music, and on-field games during breaks. Kids can also take part in the "Kids Run the Bases" event after select games, allowing them to feel like part of the action by running around the field.
Season: April to September
Location: Delta Dental Park at Hadlock Field

Maine Celtics
Minor League Basketball | NBA G League
The Maine Celtics, Portland’s very own NBA G League team, are a slam dunk for fans of all ages. As the official affiliate of the legendary Boston Celtics, they bring top-notch basketball right to Maine, giving fans a front-row seat to watch rising NBA stars in action. Players like Luke Kornet, Jordan Walsh, Neemias Queta, and Sam Hauser honed their skills right here in Portland before making their mark with the Boston Celtics. Last year, the Maine Celtics proved they’re a force to be reckoned with by making it all the way to the G League finals, solidifying their place as one of the league’s top teams.
What makes the Maine Celtics (formerly known as the Maine Red Claws) truly special is the energy and accessibility they bring to every game. There’s no need to splurge on a trip to Boston to catch professional-level hoops, because the excitement is right here in Portland. Games are fast-paced, family-friendly, and full of heart-pounding moments, from clutch three-pointers to halftime shows that keep the crowd buzzing long after the players leave the court.
