Betsey Johnson is parting ways with her huge Hidden Hills home ... and all she's asking for is a cool $7.5 mil!

The designer has listed her posh pad, which has 5 bedrooms, 4.5 baths and is 4,300-square feet.

The single-story estate, which sits on 1.5 acres of land, has a stunning view, but maybe even more impressive than the outside is the inside ... which boasts an open concept floorplan with custom cathedral ceilings and wood floors.

Oh and get this ... there's a massive barn with stables inside! Not to mention, the backyard's got a gorgeous custom pool, wood decks and an outdoor living room, so you can comfortably take in the city lights and mountain view.

The listing is held by Jordan Cohen of RE/MAX.
