New Jersey's 11th congressional district is a congressional district based in the suburbs of northern New Jersey. It is represented by Democrat Analilia Mejia, who took office on April 20, 2026. The district includes portions of Essex, Morris, and Passaic counties. It is centered in Morris County. It is the wealthiest congressional district in New Jersey and the eleventh wealthiest in the United States, with 32.9 percent of households earning over $200,000, per a 2024 study.

The 11th congressional district 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 and Joseph Minish. 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. The district became one of the most reliably Republican districts in the Northeast. It has traditionally leaned Republican but has shifted slightly more Democratic in recent years, and was represented by Democrat Mikie Sherrill from 2019. However, after winning the 2025 New Jersey gubernatorial election, she resigned from office on November 20, 2025. In a special election on April 16, 2026, Democrat Analilia Mejia defeated Republican Joe Hathaway.

Since 2023, the 11th district lost all of Sussex County, and gained several new municipalities 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.

In January 2018, 12-term incumbent Republican Rodney Frelinghuysen announced that he would not seek re-election; earlier, leading political observers had rated the district as a "toss-up" in the November 2018 election. Mikie Sherrill, a former Navy helicopter pilot and federal prosecutor, was the Democratic nominee in 2018. Assemblyman Jay Webber of New Jersey's 26th Assembly District was the Republican nominee. Attorney Ryan Martinez was the Libertarian Party nominee. On November 6, 2018, Sherrill prevailed by an unexpectedly large margin, defeating Webber 56.8%-42.1%.
