The 2018–19 Florida A&M Rattlers basketball team represented Florida A&M University in the 2018–19 NCAA Division I men's basketball season.

They played their home games at the Teaching Gym in Tallahassee, Florida, and were led by second year head coach Robert McCullum as members of the Mid-Eastern Athletic Conference.

Florida A&M is ineligible for postseason play due to failure to meet the APR multi-year threshold.

The Rattlers finished the 2017–18 season 9–25, 7–9 in MEAC play to finish in a tie three-way tie for seventh place.

9 seed in the MEAC tournament, they defeated Howard before losing to Hampton in the quarterfinals.
