Jacob is a common male first name and a less well-known surname. It is a cognate of James. Jacob is derived from Late Latin Iacobus, from Greek Ἰάκωβος Iakobos, from Hebrew יַעֲקֹב (Yaʿqob, Yaʿaqov, Yaʿăqōḇ) which is the name of a Hebrew patriarch. The name comes either from the Hebrew root עקב ʿqb meaning "to follow, to be behind" but also "to supplant, circumvent, assail, overreach", or from the word for "heel", עֲקֵב ʿaqeb.
