Pine Plains is a town in Dutchess County, New York, United States. The population was 2,218 at the 2020 census.

The name is derived from the geographic character of the region. The hamlet of Pine Plains is on the northern border of the county.

The town was part of the Little Nine Partners Patent of 1706. The town was first settled around 1740 by Moravian missionaries to the native Mahican village of Shekomeko. The town of Pine Plains was formed from the town of North East in 1823.

In the 1880s the town served as the winter-home for P.T. Barnum's animals. This was due to the rural, non-urban nature of the town (fewer prying eyes), and proximity to many different railroad lines.

In 1907, Walter W. Law moved Briarcliff Farms from Briarcliff Manor, New York, to Pine Plains and sold the property in 1918. In 1916, New York banker Oakleigh Thorne and several business partners purchased large land parcels. They began breeding Angus cattle still in the name of Briarcliff Farm. The farm was broken up into several smaller farms in the late 1940s, and most lasted until the early 1980s, closing due to property taxes and poor economic conditions. Berkshire Stud purchased 550 acres (0.9 sq mi) there, starting in 1983.

According to the United States Census Bureau, the town has a total area of 31.2 square miles (80.7 km), of which 30.6 square miles (79.2 km) is land, and 0.58 square miles (1.5 km), or 1.89%, is water. The northern town line is the border of Columbia County, with the towns of Gallatin and Ancram to the north. The town of North East borders the east, Stanford to the South and Milan to the west.

Three small lakes lie west of Pine Plain's hamlet: Stissing Lake which is excellent for swimming, Thompson Pond which is dedicated to conservation for wildlife, and Twin Island Lake, known locally as "Mud Pond". Stissing Mountain, the town's highest point at 1,403 feet (428 m), is immediately to the west. It is formed of Precambrian gneiss that remains after numerous glaciation cycles have scoured and reformed the surrounding terrain. The mountain itself is a permanent exhibit at the American Museum of Natural History, showcasing its unique formation and flora/fauna of the area.

In 2009, the town enacted its first zoning ordinance after protracted review, discussion and community input. The Comprehensive Plan was updated in 2021.

Pine Plains is the location of a two-thousand-acre farm assembled by ice cream parlor chain entrepreneur Tom Carvel. It currently, as of October 2024, listed on the market by the Durst Organization, which was planning a housing community.
