The dative case (abbreviated dat, or sometimes d when it is a core argument) is a grammatical case generally used to indicate the noun to which something is given, as in "George gave Jamie a drink".

In general, the dative marks the indirect object of a verb, although in some instances the dative is used for the direct object of a verb pertaining directly to an act of giving something. In Russian and Swiss German, for example, the verb "to call (by telephone)" is always followed by a noun in the dative.

The thing being given may be a tangible object, such as "a book" or "a pen", or it may be an intangible abstraction, such as "an answer" or "help".

In some languages, the dative case has assimilated the functions of other now-extinct cases. In Ancient Greek, the dative has the functions of the Proto-Indo-European locative and instrumental as well as those of the original dative.

Sometimes the dative has functions unrelated to giving. In Scottish Gaelic and Irish, the term dative case is misleadingly used in traditional grammars to refer to the prepositional case-marking of nouns following simple prepositions and the definite article. In Georgian, the dative case also marks the subject of the sentence in some verbs and some tenses. This is also called the dative construction.
