Attleboro is a city in Bristol County, Massachusetts, United States. It was once known as "The Jewelry Capital of the World" for its many jewelry manufacturers. According to the 2020 census, Attleboro had a population of 46,461.

In 1634, English settlers first arrived in the territory that is now Attleboro. The deed that granted them the land was written by Native American Wamsutta. The land. It included the towns of Cumberland, Rhode Island, until 1747 and North Attleborough, Massachusetts, until 1887. In 1697 in response to an unwanted amount of disturbances, mainly from nearby tribes of natives, the town had a meeting and ended up deciding that selectmen would keep tabs on strangers and foreigners as well as banning certain ones from entering the town. The town was reincorporated in 1914 as the City of Attleboro, with the "-ugh" removed from the name, although North Attleborough kept it. Like many towns in Massachusetts, it was named after a British town, in this case a market town in Norfolk, England.

During the Native American insurgency in the colonial era, Nathaniel Woodcock, the son of an Attleborough resident, was murdered, and his head was placed on a pole in his father's front yard. His father's house is now a historical site. It is rumored that George Washington once passed through Attleborough and stayed near the Woodcock Garrison House at the Hatch Tavern, where he exchanged a shoe buckle with Israel Hatch, a revolutionary soldier and the new owner of the Garrison House.

The city became known for jewelry manufacturing in 1913, particularly because of the L.G. Balfour Company. That company has since moved out of the city, and the site of the former plant has been converted into a riverfront park. Attleboro was once known as "The Jewelry Capital of the World", and jewelry manufacturing firms continue to operate there. One such is the Guyot Brothers Company, which was started in 1904. General Findings, M.S. Company, James A. Murphy Co., Garlan Chain, Leach & Garner, and Masters of Design are jewelry manufacturing companies still in operation.

In late 2003, The Sun Chronicle reported that a state investigation had been launched into the deaths of three women in the city from glioblastoma. In 2007, the State of Massachusetts issued a report concluding that although the diagnosis rate for brain and central nervous system (CNS) cancers was higher than expected when compared to statewide data, the increase was determined not to be statistically significant.

Scorecard, Environmental Defense's online database of polluters, lists seven facilities contributing to cancer hazards in Attleboro, including Engineered Materials Solutions Inc., the worst offender in Massachusetts.

In 2002, the Massachusetts Public Health Department was asked to evaluate the former Shpack Landfill, on the border of Norton and Attleboro, for its cancer risks. The investigation continued at least through 2004. The informal landfill included uranium fuel rods, heavy metals, and volatile organic compounds.

Attleboro has an area of 27.772 square miles (71.930 km), of which 26.779 square miles (69.356 km) is land and 0.994 square miles (2.574 km), or 3.59%, is water.

It is bordered by North Attleborough to the north, Mansfield and Norton to the east, Rehoboth, Seekonk, and Pawtucket, Rhode Island, to the south, and Cumberland, Rhode Island, to the west, as well as sharing a short border with Central Falls, Rhode Island through the Blackstone River. It includes the areas known as City Center, Briggs Corner, West Attleboro, East Corner, East Attleboro, North Corner, Maple Square, Camp Hebron, Oak Hill, Dodgeville, East Junction, Hebronville, Park Square, and South Attleboro.

Waterways in the city include the Ten Mile River, fed by the Bungay River, the Manchester Pond Reservoir, and several small ponds.

Attleboro's school district has five elementary schools (Hill-Roberts, Hyman Fine, A. Irvin Studley, Peter Thacher and Thomas Willett), three middle schools (Brennan, Coelho and Wamsutta), and two high schools (Attleboro High School, and Attleboro Community Academy). Attleboro High School has its own vocational division, and its football team (the "Blue Bombardiers") has a traditional rivalry with North Attleborough High School, whom they play in their Thanksgiving Day football game. Attleboro Community Academy is a night school for students aged 16–25 to obtain their high school diplomas and could not function in traditional high school. Bishop Feehan High School is a co-educational Roman Catholic high school that opened in 1961 and is named for Bishop Daniel Francis Feehan, second Bishop of the Diocese of Fall River. The city also has a satellite branch of Bristol Community College, formerly housed in the city's former high school building but since relocated to an old Texas Instruments site. Bridgewater State University opened a satellite site in Attleboro in 2009, sharing space with Bristol Community College.

The former high school building was built in the 1960s, and added wings in several renovations throughout the years. The city of Attleboro voted on whether to build a new school or renovate the building, and "reached an agreement to put proceeds from the sale toward the cost of a new high school before the $260 million was approved by voters last spring." The sale of the first Attleboro High School built in 1912 on County Street gave the city funds for the new building. The new Attleboro High School opened in 2022.

Attleboro is beside Interstate 95 (which enters the state between Attleboro and Pawtucket, Rhode Island), I-295 (whose northern terminus is near the North Attleborough town line at I-95), US Route 1, and Routes 1A, 118, 123 and 152, the last three of which intersect at Attleboro center. The proposed Interstate 895 was to run through Attleboro and have a junction at the present day I-295/I-95 terminus. When driving from Rhode Island on I-295, the stub exits before the half-cloverleaf exit to I-95.

The city is home to two MBTA commuter rail stations: one in the downtown area and one in the South Attleboro district, near the Rhode Island border.
