The 2019–20 Saint Peter's Peacocks men's basketball team represented Saint Peter's University in the 2019–20 NCAA Division I men's basketball season.

The Peacocks, led by 2nd-year head coach Shaheen Holloway, played their home games at Yanitelli Center in Jersey City, New Jersey as members of the Metro Atlantic Athletic Conference.

However, the semifinals and championship game, and all postseason tournaments, were cancelled amid the COVID-19 pandemic.

The Peacocks finished the 2018–19 season 10–22 overall, 6–12 in MAAC play to finish in a three-way tie for ninth place.

9 seed in the MAAC tournament, they upset Marist[1] before falling to Iona in the quarterfinals.
