• Jude or Judas (יהודה "Praise", Standard Hebrew Yəhuda, Tiberian Hebrew Yəhûḏāh) was the name of several people in the New Testament:

1. Judas the Zealot (Matthew 13:55; John 14:22; Acts 1:13), an apostle also called Thaddaeus or Lebbaeus (Matthew 10:3; Mark 3:18);
2. Judas Iscariot (Matthew 10:4; Mark 3:19);
3. The Judas called "the son of James" (Luke 6:16), may be the same with the Judas surnamed Thaddaeus. The only thing recorded regarding him is in John 14:22.
4. Jude Thomas, usually identified as Thomas, a brother of Jesus and James the Just. Eusebius records the fact he had two grandsons living in the time of the Emperor Domitian who shared a farm 10 acres (40,000 m²) in size worth 9000 pieces of silver.

• The Epistle of Jude contained in the New Testament of the Bible is commonly referred as Jude.

  By internal evidence, the author of the Epistle of Jude appears to be either the Apostle Jude, or Jude the brother of Jesus. However, some scholars have dated this work a couple of generations later than the time of either Jude.

• Saint Jude is the patron saint of just but hopeless causes in the Roman Catholic Church.
