Eleniak

Eleniak is a surname of Eastern European origin. The name is typically treated as a patronymic formed from a personal name such as Elena or Eleni, with the suffix -ak, a pattern common in Ukrainian and Polish surname formation. As a result, the name is most frequently found among families with Ukrainian, Polish, or Greek heritage, and has appeared in North America due to immigration in the 19th and 20th centuries.

Notable people with the surname include Erika Eleniak (born 1969), an American actress known for her work on the television series Baywatch and her film roles in the late 1980s and early 1990s.

In public records and genealogical sources, Eleniak is generally regarded as a relatively uncommon surname outside of specific regional communities, with most instances concentrated in North America.
