Lawrence Township is a township in Mercer County, in the U.S. state of New Jersey. Located at the cross-roads between the Delaware Valley region to the southwest and the Raritan Valley region to the northeast, the township is an outer-ring suburb of New York City in the New York Metropolitan area, as defined by the United States Census Bureau, while also directly bordering the Philadelphia metropolitan area and is part of the Federal Communications Commission's Philadelphia Designated Market Area.

The home of the prestigious Lawrenceville School, Rider University, and the site of the Quaker Bridge Mall, the township is a regional commercial and cultural hub of central New Jersey. As of the 2020 United States census, the township's population was 33,077, a decrease of 395 (−1.2%) from the 2010 census count of 33,472, which in turn reflected an increase of 4,313 (+14.8%) from the 29,159 counted in the 2000 census.

What is now Lawrence Township was originally formed as Maidenhead Township on February 20, 1697, while the area was still part of Burlington County in West Jersey on the eastern boundary of the Province Line (on the other side of which was East Jersey). The township was named by the early Quaker settlers after Maidenhead, a Thames River village west of London.

In 1698, Puritan settlers from Long Island and Connecticut came to Maidenhead and were granted land and established a Presbyterian church. A meetinghouse was erected on the site of the present Presbyterian Church of Lawrenceville in the early 1700s. A record from 1709 indicates that it was used both for a meeting of the Presbytery of Philadelphia and for a session of the Hunterdon County Court. The present structure was built in 1764.

The township became part of the newly created Hunterdon County on March 11, 1714. Maidenhead Township was incorporated as one of New Jersey's initial group of 104 townships by an act of the New Jersey Legislature on February 21, 1798.

In 1810, the seventh minister of the church, Isaac V. Brown, began the Maidenhead Academy to prepare young men for college. This school is now the Lawrenceville School.

On January 24, 1816, the municipality was renamed Lawrence Township, in honor of Captain James Lawrence—commander of the frigate USS Chesapeake, one of the naval heroes of the War of 1812, and a native of relatively nearby Burlington, New Jersey—best known for his dying command of "Don't give up the ship". Lawrence Township became part of Mercer County at its creation on February 22, 1838. Portions of the township were taken to form Millham Township on February 10, 1882, which was annexed six years later by Trenton.

On September 23, 2003, at approximately 8:25am, an F1 tornado ripped through Lawrence Township. The tornado followed a path along Princeton Pike and caused widespread damage to homes. There were no fatalities.

Violent crime in Lawrence Township is notably rare. A fatal shooting at an Applebee's restaurant on November 14, 2017, was the first murder in the township in 16 years.

According to the United States Census Bureau, the township had a total area of 21.98 square miles (56.94 km), including 21.73 square miles (56.27 km) of land and 0.26 square miles (0.67 km) of water (1.17%).

Lawrenceville (with a 2010 Census population of 3,887) is a census-designated place and unincorporated community located within Lawrence Township.

Many area residents often refer to all of Lawrence Township as Lawrenceville, as a significant majority of township residents use a Lawrenceville mailing address as specified by the United States Postal Service, while other residents have mailing addresses in either Princeton or Trenton. The township was notified by the Postal Service in 2007 that the preferred designation for the ZIP code 08648 would be changed to "Lawrence Township".

The township borders the Mercer County municipalities of Ewing Township, Hamilton Township, Hopewell Township, Princeton, Trenton and West Windsor.

Several major transportation routes traverse the Township. Interstate 295 runs through as a semicircle while U.S. Route 1, the other major highway, bisects the municipality. U.S. 1 is in effect three different roads: the original route from Trenton to New Brunswick in the southern half of the Township, the limited access Trenton Freeway, and the combined road in the northern half that serves as a regional arterial linking the Interstates with New Brunswick and Route 18.

U.S. Route 206 (Lawrence Road) is the main artery within the township itself, running from Trenton to Princeton roughly north-to-south. It is a segment of the historic Lincoln Highway, and before that, it was part of the main New York-Philadelphia Post road in the decades after the Revolutionary War. Major county routes that pass through include County Route 533, County Route 546 and County Route 569.

Lawrence Township had been the site of what was called the "abrupt ending" of Interstate 95. This was a result from politics in Somerset County that eliminated a planned connection of the Somerset Freeway to Interstate 287. Originally, when drivers travelled along I-95 north while approaching the interchange for U.S. Route 1, the 95 designation abruptly ended and the highway turned southward and became Interstate 295. Drivers wishing to continue north were required to use an alternate route, either by taking US 1 north, or continue along Interstate 295 south to Interstate 195 east and to the New Jersey Turnpike (Interstate 95) at Exit 7A in Robbinsville Township. This portion of interstate (between the Hopewell Township border and U.S. 1) was renumbered from I-95 to I-295 in May 2018.

The busy Northeast Corridor rail line, carrying Amtrak and NJ Transit trains, runs along the eastern edge of the township. The nearest stations are in Hamilton, Trenton, Princeton and Princeton Junction.

NJ Transit provides bus service to Trenton on the 600, 603, 605, 606, 609 and 613 routes, and local service on route 612.

A rail spur used to run to Lawrenceville from Trenton, but was discontinued in the 1970s and is now a bicycle trail. From Lawrenceville, a trolley line to Princeton existed from 1900 to 1941, but was dismantled before World War II, and the right-of-way largely has reverted to neighboring landowners.
