Meaning & origin
Glendon is a rare given name that saw its peak popularity in 1933, when it ranked highest among U.S. births. However, since 1985 its usage has been declining; in 2025 only about 1 in 142,340 boys received the name, placing it at rank 6,803. The name first appeared on U.S. records in 1904, reflecting its mid-20th-century vogue. Glendon has no strong association with any particular state and is most often encountered as a surname or a variant of the more common Glen. Its Welsh origins give it a rugged, place-based meaning that appeals to parents seeking an uncommon yet traditional-sounding name.
Glendon is a rare surname-turned-first-name, ultimately derived from a place name in Wales. The elements are likely "glen" (a valley) and "don" (a hill fort or settlement), giving the sense of a fort situated in a valley. It saw some use as a given name in the early 20th century, particularly in the United States, but has remained uncommon.
