'''Dennis''' or '''Denis''' is a first or last name from the [[Greco-Roman]] name [[Dionysius]], via one of the [[Saint Dionysius (disambiguation)|Christian saints named Dionysius]].

The name came from [[Dionysus]], the [[Classical mythology|Greek]] god of ecstatic states, particularly those produced by [[wine]], which is sometimes said to be derived from the Greek Dios (Διός, "of [[Zeus]]") and [[Nysa (mythology)|Nysos or Nysa]] (Νῦσα), where the young god was raised. Dionysus (or Dionysos; also known as Bacchus in Roman mythology and associated with the Italic [[Liber]]), the [[Thracian]] god of wine, represents not only the intoxicating power of wine, but also its social and beneficent influences. He is viewed as the promoter of civilization, a lawgiver, and a lover of peace—as well as the patron deity of both agriculture and the theatre.

Dionysus is a god of mystery religious rites, such as those practised in honour of [[Demeter]] and [[Persephone]] at [[Eleusis]] near Athens. In the Thracian mysteries, he wears the "bassaris" or fox-skin, symbolizing new life. (See also [[Maenads]].)

A mediaeval [[List of Latinised names|Latinised]] form of the Anglo-Norman surname ''Le Denys'' was ''Dacus'', which correctly meant [[Dacia]]n, but when the Vikings were about was often used to mean "Danish" or "The Dane". The name became modernised as Denys, then later as Dennis.

Alternative forms and spellings of the name include [[Denis (given name)|Denis]], Denys, Dennys, Denish, Deon, Deonne, Deonte, and Dion, Dionice. [[Diminutive]] forms include Den, Dennoh, Deno, Denny, Deny and Deen.

The name Sydenie (alternate spellings: Sydney or [[Sidney (disambiguation)|Sidney]]) may derive from a village in Normandy called Saint-Denis.{{Citation needed|date=August 2011}} A medieval diminutive was Dye, from which the names [[Dyson (surname)|Dyson]] and [[Tyson]] are derived.{{Citation needed|date=August 2011}}

Dennis is a very popular [[English people|English]], [[Irish people|Irish]] and [[Danish people|Danish]] name, common throughout the [[English-speaking world]], and a very popular [[French people|French]] name, common throughout the [[Francophone]] world. It is also common as a  [[German people|German]], [[Italian people|Italian]], [[Dutch people|Dutch]], [[Croats|Croatian]], [[Belarusians|Belarusian]], [[Ukrainians|Ukrainian]], [[Russians|Russian]], [[Bulgarians|Bulgarian]], [[Brazil]]ian, [[Bosniaks|Bosnian]], and [[Albanian people|Albanian]] name.

''Dionizy'' is the [[Polish language|Polish]] version of the name, while ''Dionigi'' and ''Dionisio'' are the [[Italian language|Italian]] versions of the name. The [[Irish language|Irish]] name [[Donnchadh]] is sometimes anglicised as ''Denis'', but has a different origin and is in fact related to the names [[Duncan (given name)|Duncan]] and Donagh. Feminine versions of the name include: [[Denise (given name)|Denise]], Denisa, Deni, Denice, Deniece, Dione, and Dionne.
