Beekman is a town in Dutchess County, New York, United States. It is part of the Kiryas Joel-Poughkeepsie–Newburgh, NY Metropolitan Statistical Area as well as the larger New York–Newark–Bridgeport, NY-NJ-CT-PA Combined Statistical Area. The population was 14,172 at the 2020 census. The town was named after Henry Beekman, a 17th-century land owner.

The "Beekman" name became attached to the area in 1697, from Henry Beekman, a Kingston native, who had a large land stake in Dutchess County. In 1697, while serving as a judge, "Beekman obtained a grant from the British crown for what was to be named the Beekman Patent," which included the present towns of Beekman, Pawling, Dover, Union Vale and "part of LaGrange." Henry was the son of Deputy Mayor of New York City Wilhemus Beekman, and also served as a delegate in the New York General Assembly beginning in 1691.

Wappinger Indians were reportedly the town's original residents before the first European settlers arrived around 1710. The Beekman Patent, granted to Beekman in 1697, was the second largest land holding in Dutchess County. In 1737, Beekman became an official precinct, and local government was established. 1788 was the initial period of establishing towns and counties in the newly independent state of New York, but parts were removed subsequently to form other towns. Beekman contributed part of its territory to the newer towns of LaGrange (1821) and Union Vale (1827). Iron ore extraction and smelting were important in the early economy. The Beekman Patent was a manor until after the Revolution. Residents could only lease the land and pay rent in wheat, fat fowls and work on roads. The series Settlers of the Beekman Patent chronicles the lives of all residents there in the 18th century.

A Lutheran church, located off Beach Road, was "probably the first house of worship" in the town. The church is "on the records from 1749" and "served the German settlers who came from the Palatine immigration." A Quaker meeting house was built in 1771 in Gardner Hollow, and was named the "Apoquague Preparative Meeting." St. Denis Church, a Catholic church located just beyond the East Fishkill line, also attracted worshipers from Beekman.

Beekman began its "boom" in the late 19th and early 20th centuries as the communities of Sylvan Lake, Beekmanville, and Clove Valley were in the active mining business. Many townsfolk that settled in town during this time were Irish men, escaping the Great Famine, and sent their families to Beekman as well. However, the mining industry died out in the late 19th century, with very few remains today. The most notable one, the "Beekman Furnace", is still intact on Furnace Road, just off Clove Valley Road.

After the demise of the mining business in the late 19th century, Beekman saw another boom in the 20th century, with housing developments such as Dalton Farm, the first gas stations, and construction of the first supermarket in town and other stores signalling the beginning of suburban development.

Today Beekman has a total population of 14,000. Comparatively few farms remain, and commerce and industry increasingly shape the non-residential areas of the town.

Beekman is located in the southeastern part of Dutchess County, about 70 miles (110 km) north of New York City.

Beekman is bordered by the towns of East Fishkill to the southwest, LaGrange to the northwest, Union Vale to the north, Dover to the east and Pawling to the southeast.

Most of the town is drained by Fishkill Creek, which flows west to the Hudson River at Beacon. The southern corner of the town is drained by Stump Pond Creek, part of the Croton River watershed that flows to the Hudson at Croton-on-Hudson.

• Sylvan Lake – A hamlet by the western town line. It is named after Sylvan Lake, which was formed during the ice age. The early Indians originally named it Poughquag, which means "round body of water". A smaller lake known as Hidden Lake is where Mr. Daniel Delany, in the late 19th century, discovered iron ore and made his fortune. He eventually bought the adjacent property, which was the entire shoreline of Sylvan Lake, and rebuilt St. Denis church for the town. Some iron ore mining also took place along the shores of Sylvan Lake in the early 1930s, and some of these retainer wall pilings are still standing and can be clearly seen from a boat. When the mine was filled with water, construction equipment and mining tools were left on the bottom, and are present today.
