Are you thinking of a specific princess? Perhaps you're thinking of:
* Princess Leia Organa: A prominent figure in the original Star Wars trilogy.
* Princess Amidala: The queen of Naboo from the prequel trilogy.
* Princess Shmi Skywalker: Anakin Skywalker's mother.
* Princess Talia: A Mandalorian princess in the Star Wars: Clone Wars series.
If you could give me more information, I can help you identify the princess you're thinking of.
