Slidell /slaɪˈdɛl/ is a city on the northeast shore of Lake Pontchartrain in St. Tammany Parish, Louisiana, United States.

Along with a younger brother, Wesley Coke Asbury Gause, Judge Wingate, and several others, he left Shallotte, North Carolina, on February 18, and arrived at Pearlington, Mississippi, on April 14, 1836.

His traveling back and forth from lumber yard to home created a road known today as Gause Boulevard, a major east–west street in the town.

The house stood until the late 1990s, and a small family burial plot still remains where John is buried between his two wives, Lydia Russ and Johanna Frederica VanHeemskerk.

Slidell was founded on the north shore of Lake Pontchartrain in 1882 and 1883 during construction of the New Orleans and Northeastern Railroad (N.O.N.E.).

The town was named in honor of American politician and Confederate ambassador to France John Slidell, and officially chartered by the Louisiana State Legislature in 1888.
