Parsippany–Troy Hills, commonly known as Parsippany (/pɑːrˈsɪpəni/ par-SIP-ə-nee[18]), is a township in Morris County, in the northern portion of the U.S. state of New Jersey.

[21] The name, Parsippany, comes from the Lenape Native American sub-tribe, which comes from the word parsipanong, which means "the place where the river winds through the valley.

[25][26][27] Since 2006, Parsippany–Troy Hills appeared eight times on Money magazine's list of "Best Places to Live in the United States", ranking 17th-best in 2006, 13th-best in 2008, 15th-best in 2012, 17th-best in 2014, fifth-best in 2016, 33rd-best in 2017,[28][29][30] 26th-best in 2018, and 15th-best in 2022.

[31][32] After the Wisconsin Glacier melted around 13,000 BCE, half of Parsippany was filled with water, as this was Lake Passaic.

Paleo-Indians moved in small groups into the area around 12,500 years ago, attracted by the diversity of plant and animal life.

Native Americans traded furs and food with the Dutch for various goods, including metal pots, knives, guns, axes, and blankets.

The English took control of New Netherland, and Morris County was included in the colonial-era Province of New York.

The Parsippany area had flat land and fertile soil, and a fresh water supply, which created a suitable location for successful farming.

From the 1730s until the beginning of the 19th century, present-day Parsippany was known as Lake Hiawatha, and included a 2,000-acre (3.125 mile) slave plantation.

The central street of Lake Hiawatha, Beverwyck Road, references the name of a Dutch slave owner and property manager, Lucas Von Beverhoudt.

[33] Generations of African slaves were forced to labor on the Beverwyck property, including Phebe Ann Jacobs.

Born enslaved in 1785 on the Beverwyck plantation, she later achieved freedom in Maine, laundering clothes for students of Bowdoin College.

Her 1856 biography, Narrative of Phebe Ann Jacobs, published posthumously, was a source of inspiration to Harriet Beecher Stowe, who authored Uncle Tom's Cabin, an anti-slavery novel.

[33] Guests at the estate included George Washington, Nathaniel Greene, and Marquis de Lafayette.

[38] Until 2000, there was a 13th ZIP code within Parsippany, eliminated with changes at the Greystone Park Psychiatric Hospital.

Around 450 million years ago, a small continent, long and thin, collided with North America, creating folding and faulting in western New Jersey and southern Appalachia.

Swamps and meadows next to oak forests created a diverse flora and fauna spectrum.

[49] Among Hispanics and Latinos, the largest ancestry groups were Colombian, 900 (1.6%), followed by Puerto Rican, 586 (1%), and Mexican, 523 (0.9%).

Additionally, 58.3% of the households consisted of married couples living together, highlighting a majority presence of traditional family structures.

Within this segment, 7.9% of individuals were aged 65 or older and living alone, reflecting a portion of elderly residents who may require different community support or services.
