New Jersey's 11th congressional district is a suburban district in northern New Jersey.^[3] The district includes portions of Essex, Morris, and Passaic Counties.^[4] It is centered in Morris County.^[5]

The 11th congressional district, along with the 12th, was created in 1913 based on the results of the 1910 census, and was centered in Essex County. The congressional seat was held by Democrats for almost 36 years under Hugh Joseph Addonizio^[6] and Joseph Minish.^[7] The 1980 redistricting shifted the focus of the district to the Republican-dominated Morris County. Republican Dean Gallo defeated 22-year incumbent Democrat Joseph Minish in 1984.^[8] The district became one of the most reliably Republican districts in the Northeast.^[9] It has traditionally leaned Republican but has shifted slightly more Democratic in recent years,^[5] and has been represented by Democrat Mikie Sherrill since 2019.^[10]

Since 2023, the 11th district lost all of its towns in Sussex County, and gained several new towns in Essex County, such as Millburn and Belleville, but otherwise still contains most of Morris County. The current version of the district is not nearly as competitive, and is significantly more Democratic.^[11]
