Whalen
An English nickname surname for someone thought to be bulky or whale-like in build, ultimately from Old English words for “whale.”
The #1,470 most common surname in the United States (2010 Census) — about 1 in every 12,725 Americans shares it.
Etymology
The surname is usually explained as a nickname based on Old English hwæl, “whale.” In the historical record it appears alongside forms such as Whalan and Whallon, and the sense seems to be figurative: a large, heavy, or ponderous person. The old dictionary evidence also links it to related nicknames like Whall and even Whalebelly, reinforcing that the name began as a physical description rather than a place-name or occupation.
History
The name is recorded in English surname collections, and later appears in Irish contexts as well, where it may have been carried by English settlers or become established locally. Variant spellings such as Whalan, Whallon, and Wholihane show that the name’s form was fluid over time. In the United States, Whalen is now the standard spelling and is especially familiar as an Irish-American surname, though the older English nickname origin remains the usual explanation in etymological dictionaries.

Fun fact
A 1912 surname dictionary glossed Whalen as a nickname for a “ponderous individual,” and even cited the comic-looking surname Whalebelly as a parallel.
