Cohasset is a small town in Norfolk County, Massachusetts, United States. As of the 2010 census the population was 7,542, and in 2017 the estimated population was 8,516.
Cohasset was first seen by Europeans in 1614, when Captain John Smith explored the coast of New England. The area was first settled in 1670 and became a town separate from Hingham in 1770, 100 years later. Previously, what is today the town of Cohasset was known as Hingham’s Second Parish. The town’s name came from the Algonquian word “Conahasset”, meaning “long rocky place”. Much of the land was originally granted to the “Conahasset Partners”.
At a special town meeting of January 1670, the shares in the new town were apportioned and divided among the new proprietors, many of whom were large Hingham landowners. The largest number of shares (35) went to Hingham Town Clerk Daniel Cushing, with the second largest (25) to Reverend Peter Hobart, Hingham’s minister. Others receiving large grants were: Capt. Joshua Hobart, Peter Hobart’s brother (18 shares); Lieut. John Smith (15 shares); Ensign John Thaxter (16½ shares); and deacon John Leavitt (with 14½ shares). The layout of the town was distinctive. Many lots were laid out in long narrow strips, facilitating more lots with road frontage, and avoiding back lots.
Cohasset was originally part of Suffolk County, and when the southern part of the county was set off as Norfolk County in 1793, it included the towns of Cohasset, Hingham and Hull. In 1803, Hull and Hingham opted out of Norfolk County and became part of Plymouth County, leaving Cohasset as an exclave of Norfolk County.
Cohasset operates its own school department for the town’s approximately 1,500 students. The Osgood Elementary School serves students from pre-kindergarten through second grade. The Deer Hill Elementary School, located adjacent to the Osgood School, serves students from grades 3–5. The town operates a combined Middle/High School, which is located just over Bear Hill from the other two schools. Cohasset’s athletics teams are known as the Skippers, and their colors are navy blue and white. They compete in the South Shore League, and their chief rival is Hull High School.
The athletic programs offered to Cohasset High School students include Baseball, Ice Hockey, Basketball, Cross Country, Tennis, a Competitive Debate Team, Football (which won the 2014 Division VI Super Bowl, and made it to the 2013 Division VI Super Bowl, but lost), Soccer, Competitive Swimming, Track and Field, Sailing, Ski Team, Wrestling and Lacrosse.
High school students may also choose to attend South Shore Vocational Technical High School in Hanover free of charge. There are no private schools in Cohasset, but there are several in neighboring Hingham and the towns west of it.
