The 2019–20 Nicholls Colonels men's basketball team represented Nicholls State University in the 2019–20 NCAA Division I men's basketball season.

The Colonels, led by second-year head coach Austin Claunch, played their home games at Stopher Gymnasium in Thibodaux, Louisiana as members of the Southland Conference.

They were set to take on Lamar in the second round of the Southland tournament until the tournament was cancelled amid the COVID-19 pandemic.

Since only the top eight teams are eligible for the Southland tournament, they failed to qualify.
