The 2018 Myanmar National League, also known as the 2018 MPT Myanmar National League, is the 9th season of the Myanmar National League, the top Burmese professional league for association football clubs since its founding in 2009. The departure of the two clubs from the MNL-1 disrupted the previous season. More disruption came when Nay Pyi Taw and City Yangon withdrew from the competition towards the end of the 2017 season. At an emergency meeting of the MNL committee on September 12, Nay Pyi Taw was expelled from the league after its players complained of not having been paid since April. The expulsion came after players boycotted a game in early September. An unsuccessful coup attempt in Turkey in July last year created a crisis for City Yangon that forced its departure from the MNL. It was a big disappointment for the club, which won the 2017 MNL-2 championship to end the season undefeated. MNL-2 third-place winners Myawady FC were promoted along with runners-up Sagaing United to the 2018 Myanmar National League.
In the lead up to the 2018 season, the MNL signed a three-year sponsorship deal with the country's biggest TelCo MPT that will support funds for the Myanmar National League, MNL-2 and the youth competitions up until the 2020 season.

The table lists the positions of teams after each week of matches. In order to preserve chronological evolvements, any postponed matches are not included in the round at which they were originally scheduled, but added to the full round they were played immediately afterwards. For example, if a match is scheduled for matchday 13, but then postponed and played between days 16 and 17, it will be added to the standings for day 16.
