He was a soldier, ship captain, explorer, colonial administrator, knight of the Order of Saint Louis, adventurer, privateer, trader and Father of Louisiana. He participated in the bitter border wars with New England mounted by Frontenac, and was also active against English fur trading and ports on James Bay, raiding posts there in 1688, 1690 and 1694, and commanding his ship, "Pelican" sank two English warships near York Factory in 1697. Between 1698 and 1702 he led expedition to Louisiana planting forts there and in Alabama. His last campaign was conducted in 1706 against the English West Indian Colony of Nevis. He died of yellow fever that year. He was the first native born Canadian to receive the Croix de Saint-Louis for valor from the French crown.

Lake Pontchartrain is a brackish estuary located in southeastern Louisiana. It was founded by D'Iberville in 1699 who named it "Pontchartrain" after Louis Phelypeaux, comte de Pontchartrain, who was the French Minister of the Marine, Chancellor of France and Controller-General of Finances during the reign of France's "Sun King", Louis XIV, for whom the colony of La Louisiane was named.

Lake Maurepas is located in southeastern Louisiana approximately halfway between New Orleans and Baton Rouge directly west of Lake Pontchartrain. It was founded by D'Iberville in 1699 who named it after Jean-Frederic Phelypeaux, comte de Maurepas, an 18th Century French statesman, chief adviser to King Louis XVI. He was the son of Louis Phelypeaux, comte de Pontchartrain for whom Lake Pontchartrain is named.

D'Iberville was the first to discover the bayou in Louisiana when he made the first recorded European of the Bayou Manchac and Amite River to the Gulf of Mexico after learning of it from the Bayogoula Indians. He and his company entered Bayou Manchac from the Mississippi in Canadian bark canoes on March 24, 1699 and spent their first night on the banks of Bayou Manchac in the area of Alligator Bayou.

Baton Rouge is the capital of Louisiana. It was founded by D'Iberville in 1699 when he led a party up the Mississippi River and saw a reddish cypress pole festooned with bloody animals and fish; it marked with the boundary between the Houma Tribe and the Bayogoula hunting grounds. The French called the landmark tree "le baton rouge", (red stick). The French city of Baton Rouge became one of the more permanent of the few settlements of New France after permanent settlement began in 1719 with the building of a fort.

The brown pelican has a connection to Louisiana. From D'Iberville's first coasting of the Gulf of Mexico's shores in search of the Mississippi's mouth in 1699, journals kept by those in his company recorded the populous colonies of the birds they encountered. After returning to France, D'Iberville would captain a ship christened "The Pelican" back to New France in 1704, carrying with him some 24 "well-bred girls to the burgeoning colony of Louisiana in hope that they would provide on incentive for permanent settlement. The pelican feeding its young could be found in the Louisiana's seal as early as 1804. And the state flag of Louisiana has been displayed the white pelican feeding hatchlings since 1912. In 1966, the pelican received its ultimate due when it was officially named the State Bird of Louisiana. Yet in the very year, it was adopted as the state bird, the brown pelican that had been recorded by D'Iberville's men and itself, no less an authority then the painter and naturalist John James Audubon would describe the pelican as "one of the most interesting of our American birds", waxing rhapsodic as he went on to describe the species feeding habits in his journal.

There have some of those sites named for him that are:

Mont Iberville, the highest mountain in Quebec
Iberville Parish, Louisiana
Rue Iberville in New Orleans, Louisiana

And there have the statues of him at the Parliament Building in Quebec, Quebec, Valiants Memorial in Ottawa, Ontario and Biloxi, Mississippi.
