Zelda
Diana of Themyscira

 

[M.L. Martin]

We haven't heard listed Snow White or Guinevere yet...

Guinevere's a queen, not a princess; different archetype and narrative space.

Not to quote the OP, but quoting the OP

Rules: they have to be some sort of aristocrat in the media. Empresses, Queens, Duchesses all good.

Fair enough; I was relying more on title than on OP for my assumption of why she hadn't shown up.

Dejah Thoris (and Thuvia, too)
Kori'andr (or Maxima, to choose two from DC who aren't Diana)
Cordelia VorKosigan (and pretty much all her daughter-in-laws)

If you need another DC choice, there's always Perdita and Queen Bee. Technically Terra counts, though she rarely does anything Princess-like.

She gets into inappropriate sexual relationships that the media* tries to hush up, so there's that.

* DC Comics, in this case.

Ah yes, uh, it's never a good idea to get into a relationship with Slade Wilson.

My 6 year old great niece just told me on the weekend that Peach is her favourite Mario character.

Edited to add: So I agree she's got real intergenerational appeal.
