Marianas Soccer League 1

The Marianas Soccer League 1 is the men's top level professional football competition of the Northern Mariana Islands Football Association. It is above the Marianas Soccer League 2, but there is no regular promotion/relegation between the two competitions.

History
The league began as an invitational event in the Northern Mariana Islands. The league has been operating since 2005 and grew to include eight teams in the 2008 season.

On 2 August 2012 the competition was re-branded as the M-League, following the suit of many other AFC national competitions. In September 2012, the Northern Mariana Islands Football Association (NMIFA) officially launched a two tier completion, usually without promotion and relegation. In the inaugural season there were 5 teams in Division 1 and 4 teams in generally amateur Division 2.

After the 2020 season was abandoned due to the COVID-19 pandemic, the league was relaunched in Spring 2021 as the Marianas Soccer League.
