Martin is a common given and family name in many languages. It comes from the Latin name Martinus, which is a late derived form of the name of the Roman god Mars, the protective godhead of the Latins, and therefore the god of war. The meaning is usually rendered in reference to the god as "of Mars", or "of war/warlike" ("martial").
It has remained a popular given name in Christian times, in honor of Saint Martin of Tours; it is also the most common French surname. Along with its historic Catholic popularity, it has also been popular among Protestants due to Martin Luther. In addition, African American children are often given the name in honor of Martin Luther King, Jr.. Additionally, many Black Americans have the name Martin as a family name.
