Arabic (جعفر) "little river".

Ja‘far ibn Abī Tālib (Arabic: جعفر ابن أبي طالب / جعفر الطيار) (died 629), also known as Ja‘far at-Tayyār, was the son of Abu Talib ibn 'Abdul Muttalib (the uncle of the Islamic prophet Muhammad), and the elder brother of the fourth Sunni and first Shia caliph, Ali ibn Abi Talib. Jafar was raised by his uncle, Abbas ibn 'Abdul Muttalib, for his father was a poor man and had to support a big family. He embraced Islam in around 613.
