Northeast Conference baseball tournament

The Northeast Conference baseball tournament is the conference baseball championship of the NCAA Division I Northeast Conference (NEC). In the current format, established in 2023 after the NEC absorbed the former baseball league of the Mid-Eastern Athletic Conference (MEAC), the top six regular-season finishers among teams eligible for postseason competition advance to the double-elimination tournament. The winner of the tournament, if eligible to participate, receives an automatic berth to the NCAA Division I Baseball Championship.

Among current NEC baseball members:

Fairleigh Dickinson is the only one of these schools to have been an NEC member before the 2019–20 school year. Merrimack first became eligible for the NEC tournament in the 2023 season, having begun a transition from Division II when it joined the NEC in 2019, but did not qualify for that tournament. The other four schools, all full MEAC members, joined NEC baseball for the 2023 season when the NEC absorbed the MEAC baseball league.
 * Stonehill will be eligible for the NEC tournament for the first time in 2025, and Le Moyne in 2026.
