New Jersey's 11th congressional district is a suburban district in northern New Jersey.[3] The district includes portions of Essex, Morris, Passaic, and Sussex Counties;[4] it is centered in Morris County.[5] 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.[6]

The 11th congressional district (together with the 12th) was created in 1913 based on the results of the 1910 United States Census.^{[citation needed]} Prior to a redistricting in the early 1980s, the 11th congressional district was centered in Essex County.^{[citation needed]} The congressional seat was held by Democrats for almost 36 years under Hugh Joseph Addonizio[7] and Joseph Minish.[8] The 1980 redistricting shifted the focus of the district to the Republican-dominated Morris County.^{[citation needed]} In 1984, Republican Dean Gallo defeated 22-year incumbent Democrat Joseph Minish.[9] The district became one of the most reliably Republican districts in the Northeast.[10]

On December 22nd, 2021, the New Jersey Redistricting Commission adopted a new congressional map that will take effect in January 2023 for the following decade. In this map, the 11th district will lose all of its towns in Sussex County, and gain several new towns in Essex County, such as Millburn and Belleville, but will otherwise still contain most of Morris County. The new version will no longer be nearly as competitive, and will be significantly more Democratic.[11]

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.[17] Mikie Sherrill, a former Navy helicopter pilot and federal prosecutor, was the Democratic nominee in 2018. Assemblymember Jay Webber of New Jersey's 26th Assembly District was the Republican nominee. Attorney Ryan Martinez was the Libertarian Party nominee.[18] On November 6, 2018, Sherrill prevailed by an unexpectedly large margin,[19] defeating Webber 56.8%-42.1%. The district shifted 33% towards the Democrats; this was the largest partisan swing of any congressional district in the nation in 2018.[19]
