Aladdin (Arabic: علاء الدين‎‎, Alāʼ ad-Dīn), is a poor and lazy boy living in China with his mother in Aladdin and the Wonderful Lamp. A sorcerer pretends to be his uncle to get him to enter a cave and retrieve a lamp, but Aladdin won't give the lamp to him and asks to be helped out of the cave first. The sorcerer leaves him there, but Aladdin discovers the Genie of the Ring and wishes to go home. Afterwards, he discovers the Genie of the Lamp. He falls in love with the Princess Badroulbadour upon seeing her, and sets out to marry her.

Aladdin's name means "nobility of faith" or "nobility of religion", and is one of many names ending with ad-Din.
