2023 Martyr's Memorial A-Division League

The 2023 Martyr's Memorial A-Division League (Nepali: शहीद स्मारक ए डिभिजन लिग २०७९) was the 45th edition of the Martyr's Memorial A-Division League since its establishment in 1954–55. A total of 14 teams competed in the league.

Machhindra F.C. were the defending champions.

The league was scheduled to begin on 10 January 2023 but was pushed back to begin on 3 March 2023 due to a conflict between the All Nepal Football Association and the clubs regarding up-front payments.

On 6 June 2023, Church Boys United were crowned as league winners for the first time in club history in what the Kathmandu Post called a "fairytale run," resulting in the team winning the title for three consecutive seasons after being promoted in the two years prior respectively. However, as the champions could not secure AFC club licensing, the second-placed team Machhindra F.C. was qualified for the 2023–24 AFC Cup preliminary round 1.

The season would also be the first time that one of Nepal's three departmental clubs consisting of outfits of the Army, the Police and the Armed Police Force would be relegated with the last team coming second to last and being relegated to the Martyr's Memorial B-Division League.
