Katonah was a Lenape sachem who led parts of two bands of Wappinger in what is today the far southeastern part of mainland New York State and southwestern Connecticut: the Wiechquaeskeck in the Greenwich, Stamford areas of Connecticut, and the Ramapo inhabiting that of today's Bedford, New York.

[1] Katonah was the sachem of the condensed remnants of a Wappinger people called the Ramapo (whose descendants today, largely in New Jersey, are known as the Ramapough Mountain Indians.

Records show that in 1708 the Ridgefield settlers petitioned the colonial General Assembly at Hartford to remove the Ramapo.

Katonah sold the Ramapo lands of 20,000 acres for 100 Pounds Sterling to the "Proprietors of Ridgefield".

[11] In 2007, Martha Stewart Living Omnimedia applied for a trademark on the Katonah name for a line of furniture.
