New Jersey's 11th Congressional District is represented by Republican Rodney Frelinghuysen. The district is centered in Morris County, with suburban settlements and a high per capita income; it is dominated by Republicans. The territory is located in the area of the Watchung and Ramapo Mountains.

Prior to a redistricting in the early 1980s, the 11th was centered in Essex County. The congressional seat was held by Democrats for over 40 years. The redistricting, conducted under a Republican-dominated legislature, shifted the focus of the district to Morris County, whose population was dominated by Republicans. In 1984, Republican Dean Gallo defeated 22-year incumbent Democrat Joseph Minish. Since then, the district has been one of the most reliably Republican districts in the Northeast. The Democrats have not made a serious bid for the seat since Minish's defeat.

For the 113th and successive Congresses (based on redistricting following the 2010 Census), the district contains all or portions of four counties and 54 municipalities.

Morris County:

Passaic County:

Sussex County:

The 11th congressional district (together with the 12th) was created starting with the 63rd United States Congress in 1913, based on the results of the 1910 United States Census.

Frelinghuysen won in 2006 by 62% to 37% for a little-known Democrat named Tom Wyka. In 2010 Frelinghuysen defeated the Democratic candidate, veteran Douglas Herbert, by a large margin of 67% to 31%.
