Brewster /ˈbruːstər/ is a town in Barnstable County, Massachusetts, United States, Barnstable County being coextensive with Cape Cod. The population of Brewster was 10,318 at the 2020 census.

Initially settled in 1659, the Town of Brewster is named after Elder William Brewster, the religious leader of Plymouth Colony. Brewster is known as the "Sea Captain's Town" for its wealth of eighteenth and nineteenth century historic captain's homes, including the Cobb House (1799), the current home of the Brewster Historical Society.

Brewster is also notable as the home of Nickerson State Park, a 1,900 acre preserve carved out of the former hunting grounds of the prominent Nickerson Family. The impact of the Nickerson Family can be seen at the Nickerson Mansion, now the home of Ocean Edge Resort. Constructed in 1890, the structure known as Fieldstone Hall was considered one of the most expensive houses built in the country at that time.

The town is a popular summer destination, with the town population increasing to 30,000. It also contains two National Historic Districts: Brewster Old King's Highway Historic District and Stony Brook–Factory Village Historic District, both listed on the National Register of Historic Places.

Brewster is twinned with the town of Budleigh Salterton in the United Kingdom.

Indigenous settlement in Brewster took place on the north shore of the present-day town, with a Sauguatuckett farming area centered around the contemporary Stony Brook. Individual accounts subdivide the indigenous tribes of pre-contact Cape Cod, but any historians and researches today use the unifying term Nauset. Somewhere around 1,200 indigenous people populated Outer Cape Cod prior to 1617 pandemics, with this number reduced to 500 by 1621. The first permanent colonial settlement in Brewster centered around the Stony Brook area, part of the "Old Comers" or "Purchasers" grant of 1641. The land that now makes up Brewster was purchased in 1653 from Wano and his son Sachemas, leaders of the local Sauguatuckett. By this period, the Sauguatuckett held significant quantities of corn, beans, and squash which were at times for sale to English settlers. Brewster was first officially settled in 1656 as a northeastern parish of the town of Harwich. However, at the turn of the eighteenth century, there were only seventeen known male settlers in what is now Brewster.

Brewster's first settlers came from Sandwich, Plymouth, and Eastham, as well as many arriving directly from England. Throughout the 1700s, there were interspersed agricultural settlements throughout the area now known as Brewster. The Stony Brook gristmill remains as a testament to the early manufacturing activity at this site. In 1709, a public house and store existed, with a congregational church and meeting house first organized in 1700. By 1750, there were around 190 settlers living in the Brewster environs. The remaining indigenous population in Brewster consolidated around the southwestern corner of the town. Settlers and indigenous people alike utilized the abundant cornfields, as well as the natural resources of Cape Cod Bay. Substantial amounts of herring, or alewife, were, and continue to be, found in the Stony Brook area.

Brewster was officially incorporated as its own town in 1803 when the less wealthy citizens of Harwich were upset that the town's institutions were all concentrated on Brewster's Main Street, now Route 6A, including the town hall and churches. Brewster was named in honor of Elder William Brewster, the first religious leader of the Pilgrims at Plymouth Colony.

By this period, roughly 75% of town inhabitants were involved in shipping and maritime trades. Brewster captains invested an estimated $250,000 on merchant vessels, and a large saltworks was present on the shoreline of Cape Cod Bay during this period. In 1865, Brewster maintained 56 farms, the highest of any town on the Lower Cape aside from Orleans. At this time, Brewster also had the third highest number of cranberry bogs on the Cape, following Harwich and Dennis. Architecturally, Brewster blossomed during this period, with wealthy sea captains and commercial titans constructing Italianate, Greek Revival, and Second Empire homes. The most emblematic structure of this period is Albert Crosby's 1888 Crosby Mansion, located on Crosby Lane.
