[Denver]

Apologies to Will Smith ... the 'Fresh Prince of Bel-Air' might be getting dethroned soon, 'cause there's a potential new heir being eyed for a TV reboot -- and he's a she ... TMZ has learned.

The company that owns the rights to 'Fresh Prince' filed a few trademark applications seeking to lock down rights to "Fresh Princess" for a television program and virtually every other media platform.

They're also looking to trademark the "Fresh Princess" on a bunch of merch -- including bags, backpacks, animal collars and, of course, lots of clothing and footwear.

As we reported ... the folks in control of 'FP' recently wanted trademarks for new 'Fresh Prince' toys, which fueled speculation a cartoon version of the hit '90s show was on the horizon ... especially since Will seemed to endorse an animated take on the Banks.

No word on whether Will would be involved with a female-focused reboot.
