A MP will raise in Parliament whether rules should be changed to let a future female heir to the throne take the title Princess of Wales.
Caerphilly MP Wayne David said it was important to "move with the times".
Currently women are superseded by their brothers even if they are first born, but legislation is planned to allow the first born to inherit the crown whether male or female.
Mr David told Oliver Hides of BBC Radio Wales he wants to take this a step further and ensure a female heir apparent can be called the Princess of Wales.
