Glynn is an unincorporated community in southeastern Pointe Coupee Parish, Louisiana, United States.
In 1847, an Irishman named Martin Glynn immigrated to New Orleans, Louisiana and set himself up as a wholesale merchant, grocer, and cotton factor.
As his fortune grew, Glynn purchased property in West Baton Rouge and Pointe Coupee parishes.
After the Civil War, Glynn moved his growing family to the 3,000 acres (12 km2) he had acquired.
Around the turn of the century, the Texas and Pacific Railroad began laying track through his property, and on December 23, 1899, a post office was established.
