Marija is a feminine given name, a variation of the name Maria, which was in turn a Latin form of the Greek names Μαριαμ, or Mariam, and Μαρια, or Maria, found in the New Testament.

Depending on phonological rules concerning consecutive vowels or the use of the palatal approximant, "Mary" in these languages is Marija if consecutive vowels are disallowed and otherwise Maria.

Marija is the most common female name in Croatia.

[2] The male equivalents are Marijan, Marijo and Mario.
