William Windham (of Earsham, senior)

William Windham (1657-1730), of Earsham Hall, Norfolk, was a British landowner, politician, and member of Parliament. He is often referred to as "senior" to distinguish him from his grandson, William Windham (1750-1810), the prominent statesman. He represented Norfolk in Parliament from 1698 to 1701 and again from 1702 to 1708, and subsequently Sudbury from 1708 to 1710.

Windham came from a long-established Norfolk family. His political leanings were generally Tory, aligning him with the country party. He was known for his independent stance and occasional opposition to government policies.

His principal residence was Earsham Hall, which he inherited and maintained as a significant estate. His son, William Windham (1688-1761), continued the family's political involvement. The "senior" designation is primarily used by historians and genealogists to clearly differentiate him from his more famous grandson of the same name.
