Saybrook Colony formally joined Connecticut in 1644. The portion of the original colony east of the Connecticut River was set off as a separate town in 1665. The site of the present village of Deep River was said to have been owned by John, Nathaniel, and Philip Kirtland in 1723.^[3] The village of Winthrop was said to have been settled by Baptists as early as 1729.^[3] In the early to mid-19th century, various portions of Saybrook broke off as separate towns, starting from Chester in 1836 to Old Saybrook in 1854. In 1947, the town of Saybrook changed its name to "Deep River", matching the name of the town center village. The name "Deep River" was taken from the river/stream that once powered mills and factories that runs through it and not from the Connecticut River that is its eastern border. The actual Deep River stream begins at the border of its neighboring Town of Chester, in the western Winthrop section of town, on Cedar Swamp Road and flows through town to the stream that can be seen on Route 154, near Winter Avenue, empty onto the cove that connects to The Connecticut River. ^[4][5]

Saybrook Colony, along the mouth of the Connecticut River, was one of the early settlements in the area. Several towns broke off and incorporated separately over the course of time. The towns which were created from parts of Saybrook Colony are listed below.

• Lyme (originally East Saybrook) in 1665
  • East Lyme created from Lyme in 1839 (also partly from Waterford)
  • Old Lyme (originally South Lyme) created from Lyme in 1855
• Chester in 1836
• Westbrook in 1840
• Essex (originally Old Saybrook) in 1852
  • Old Saybrook created from Essex in 1854

From 1840 to circa 1940, the U.S. was the world's biggest buyer of ivory and most of that ivory went to Deep River. Phineas Pratt developed an ivory lathe and eventually Deep River became known as "the queen of the valley" due to wealth from the ivory industry.^[6] The rival Comstock, Cheney & Company was established in nearby Ivoryton in the 1860s.
