According to Daniel, what new name did the Babylonian official give Daniel?

According to Daniel, the Babylonian official gave Daniel the name Belteshazzar.

Daniel 1 says that the king’s chief official assigned new Babylonian names to Daniel and his three Judean companions. Daniel was called Belteshazzar, while Hananiah, Mishael, and Azariah received the names Shadrach, Meshach, and Abednego.

The renaming occurs after young Judeans are brought to Babylon and selected for royal training. The narrative emphasizes their education, diet, wisdom, and loyalty to the God of Israel while they serve within the Babylonian court. Daniel later becomes known for interpreting dreams and visions.

A frequent mix-up is using one of the companions’ names for Daniel. Shadrach belongs to Hananiah, Meshach to Mishael, and Abednego to Azariah. Belteshazzar is also easily confused with Belshazzar, the Babylonian king in Daniel 5; the names are similar but refer to different people.
