I'm not recommending all these for quality, but some that spring to mind outside of De Palma and the ones listed in the notes.
High Anxiety (a parody)
Psycho (1998) (a remake)
Gaslight (1944)(the british version too but less so, though I prefer it.)
What Lies Beneath
Gone Girl; possibly Zodiac and Se7en as well...even Panic Room to some degree, given all the survelliance and peeping. Ill throw out The Game as well even though I haven't seen it in ages. Fincher might be an underrated director influenced by Hitchcock looking back.
The Hand That Rocks The Cradle (edit: maybe others can think of other Curtis Hanson movies? To me, this seems the clearest)
Mulholland Drive (didn't occur to me until way later, but Lynch has been a big Hitchcock advocate and I can see why when thinking about this movie; Blue Velvet possibly too but this one even more)
Shutter Island (definitely some differences and twists, but it's the most strongly, imo, Hitchcock-esque Scorsese movie, though one could argue for Cape Fear too)
The Conversation (not as sure about this one, but seems worth throwing out there for discussion)
The Spanish Prisoner
Flightplan (lots of psychological elements, ummmm themes since I won't give spoilers although I'm not crazy about this movie at all)
Disturbia (obvious [bad] knockoff remake of Rear Window)
Jaws (? maybe some will dispute this one, but I put it because of the suspense moments and the techniques used at various points, also the shark's reign of terror is never explained)
Basic Instinct (I don't know what to call this one exactly, but the influence is there in the shots, twists, suspense, the blonde, etc.)
