Oradell was originally formed on March 8, 1894, as the borough of Delford, from portions of Harrington Township, Midland Township and Palisades Township. The borough was formed during the "Boroughitis" phenomenon then sweeping through Bergen County, in which 26 boroughs were formed in the county in 1894 alone. The name "Delford" was a portmanteau created from the names of two communities within the new borough: Oradell and New Milford. The Hotel Delford had been constructed in 1870 after the construction of the first railroad to reach the area. On November 12, 1920, the borough's name was officially changed to "Oradell", based on the results of a referendum held ten days earlier. Oradell derives from "ora" (Latin for "edge") and "dell".
New Jersey Monthly magazine ranked Oradell as the 68th best place to live in New Jersey in its 2010 rankings of the "Top Towns" in the state. This ranking also makes the borough the seventh best place to live in Bergen County.
Oradell Reservoir was formed by the Oradell Reservoir Dam placed on the Hackensack River, which was started in 1921 and finished in 1923. The reservoir is fed by the Pascack Brook and Dwars Kill in addition to the Hackensack River. The Dam has greatly reduced the amount of flooding in the eastern part of Oradell caused by the Hackensack River, though it also resulted in the loss of flora and fauna that depended on the fresh water that flowed down the river. Fed by rain from Hurricane Irene in August 2011, the water level in the reservoir was two feet above the top of the dam, allowing billions of gallons of water to flow over the dam and exacerbating flooding conditions in Oradell and New Milford.

Oradell is governed under the Borough form of New Jersey municipal government. The governing body consists of a Mayor and a Borough Council comprising six council members, with all positions elected at-large on a partisan basis as part of the November general election. A Mayor is elected directly by the voters to a four-year term of office. The Borough Council consists of six members elected to serve three-year terms on a staggered basis, with two seats coming up for election each year in a three-year cycle. The Borough form of government used by Oradell, the most common system used in the state, is a "weak mayor / strong council" government in which council members act as the legislative body with the mayor presiding at meetings and voting only in the event of a tie. The mayor can veto ordinances subject to an override by a two-thirds majority vote of the council. The mayor makes committee and liaison assignments for council members, and most appointments are made by the mayor with the advice and consent of the council.
As of 2014[update], the Mayor of Oradell is Joseph L. Murray, Jr. (R, term of office ends on December 31, 2015). Members of the Borough Council are Council President Edward Pfleging (R, 2014), Donna Risse Alonso (R, 2015), James G. Koth (R, 2015), Garrie Murphy (R, 2016), Eric Shuler (R, 2016) and Michael Staff (R, 2014; serving an unexpired term).
Michael Staff was named to fill the vacant seat of Antonio B. Meo, who resigned from office in December 2013 following his marriage and planned move out of the borough.
