Ylönen

Ylönen is a Finnish surname. It uses the common suffix -nen and is often derived from a place name or descriptive element. The root element yli- is related to the Finnish word yli meaning "over" or "above," though the precise origin can vary and may reflect a local toponym or geographic feature.

Historically, Ylönen appears in Finland after the adoption of fixed surnames in the 19th century and is most commonly found among Finnish-speaking populations. Today it is predominantly found in Finland but is also present in Finnish diaspora communities abroad, notably in Sweden and North America, where emigration from the late 19th to mid-20th centuries spread Finnish surnames.

The surname is borne by numerous individuals in Finnish society across fields such as education, sports, arts, and business, though no single figure is universally associated with it. As with many Finnish names, genealogical research can reveal regional concentrations and family lines.
