Mary is a feminine given name, the English form 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. Both New Testament names were forms of the Hebrew name מִרְיָם or Miryam.

The usual meaning given by various sources for the name is the Hebrew מרר m-r-r meaning "bitterness". Other meanings suggested include "rebelliousness" (מרי m-r-y), or "wished for child" or "Our Lady" (ש"ע מריה Sha Mrih) or "beloved lady", referring to the Christian reverence for the Virgin Mary. The Web site Behind the Name notes that the name could also be a name of Egyptian origin, perhaps from the word elements mry, meaning "beloved" or mr, meaning "love".

The name was also considered in the Middle Ages to be connected to the sea and the word mare, as in the term Stella Maris, or "star of the sea," an epithet for the Virgin Mary.

The name has been widely used due to its associations with the Virgin Mary, mother of Jesus Christ, and with Saint Mary Magdalene, who was called an apostle to the Apostles.

A given name, in Western contexts often referred to as a first name, is a personal name that specifies and differentiates between members of a group of individuals, especially in a family, all of whose members usually share the same family name (surname). A given name is purposefully given, usually by a child's parents at or near birth, in contrast to an inherited one such as a family name.

In most European (and Europe-derived) cultures, the given name usually comes before the family name (though generally not in lists and catalogs), and so is known as a forename or first name; but the family name traditionally comes first in Hungary, parts of Africa and most of East Asia (e.g. China, Japan, Korea and Vietnam). In East Asia, even part of the given name may be shared among all members of a given generation in a family and the family's extensions, to differentiate those generations from other generations.

Under the common Western naming convention, people generally have one or more forenames (either given or acquired). If more than one, there is usually a main forename (for everyday use) and one or more supplementary forenames; but sometimes two or more carry equal weight. Beyond preceding the surname there is no particular ordering rule for forenames. Often the main forename is at the beginning, resulting in a first name and one or more middle names, but other arrangements are quite common.
