Westwego is a city in the U.S. state of Louisiana, located in Jefferson Parish. It is a suburban community of New Orleans in the Greater New Orleans metropolitan area and lies along the west bank of the Mississippi River. The population of the city of Westwego was 8,568 at the 2020 United States census.

One story states that Westwego was so named because it was a major crossing point on the Mississippi River during the great westward movement of the late 19th century. When travelers were asked their destination, they would often reply "west we go". Another more specific tale, recounted in John Churchill Chase's Frenchmen, Desire, Good Children is that the name was the specific outcome of an 1871 meeting of a railroad board of directors in New York, where planning was undertaken to use the site as an eastern terminus ("...west we go from there"). There has been further speculation that this use of "Westwego" as a place name may have been influenced by the board members' familiarity with the name of Oswego, New York.

The area of Westwego, Louisiana was inhabited by Native Americans for thousands of years before Europeans settled here. These indigenous people created huge shell middens that can still be seen in the vicinity today. The French first developed the area in 1719 when French minister of state Claude le Blanc started a plantation and a port along the Mississippi River.

The port became an important site in the history of the transatlantic slave trade. The estate was later owned by the Zeringue family, who turned it into bustling sugar plantation, known as Seven Oaks. Planter Camille Zeringue built a canal at the plantation that played a prominent role in the community's history for decades. Other antebellum plantations in the area included the Whitehouse Plantation, Magnolia Lane, and the LaBranche Plantation among others. After Camille Zeringue's death, Seven Oaks was owned by Pablo Sala, who divided the property along the canal into lots, which he sold for $40 each. Many of these lots were purchased by displaced hurricane victims from Cheniere Caminada whose homes were destroyed in the great unnamed 1893 storm. With the addition of these families, who were mostly fisherman and trappers, the community of Salaville was born.

Salaville grew and the local railroad barons coined the name "Westwego". A number of industries grew around the city's wetlands and bayous, including those involving fisheries, shrimping, the canning of seafood, etc. Westwego was incorporated as a city in 1951 as its population continued to grow and grow. Within the last decade, Westwego has taken on a number of historical restoration projects, inspired by historian Daniel P. Alario Sr.

On December 23, 1977, the Continental Grain Elevator in Westwego exploded. The explosion and resulting collapse of the elevator killed 36 people and injured at least 11 others. Most of the fatalities were caused by a concrete tower collapsing onto an office building, where workers were gathered for a Christmas party. The explosion is believed to have been caused by the ignition of grain dust. The blast caused silos to fall and lean against each over in essentially a domino effect. The accident is the deadliest grain elevator accident in history. The Westwego accident, along with other explosions that occurred within the two-year period, led to new regulations for preventing dust explosions.
