The 2023–24 NIFL Premier Intermediate League (known as the  Playr-Fit Premier Intermediate League for sponsorship reasons) was the seventh season of the NIFL Premier Intermediate League (the third tier of the Northern Ireland Football League - the national football league in Northern Ireland). The season began on 26 August 2023 and concluded on 27 April 2024.

The winners (Limavady United) were promoted to the 2024–25 NIFL Championship. The runners-up (Armagh City) were also promoted after winning the NIFL Championship play-off. The bottom-placed team (PSNI) were relegated to Level 4.

Teams
The league consisted of fourteen teams; eleven teams remaining from the previous season, two teams promoted from Level 4, and one team relegated from the NIFL Championship. The two promoted teams were Coagh United (champions of the 2022–23 Ballymena & Provincial Football League) and Rathfriland Rangers (champions of the 2022–23 Northern Amateur Football League), increasing the number of teams by two. The relegated team was Warrenpoint Town, who were relegated from the 2022–23 NIFL Championship due to a licensing issue (replacing the promoted team of Bangor).

Results
Each team plays every other team twice (home and away).
