The Aft Grand Staircase was a First Class area of the RMS Titanic. A staircase similar to the Fore Grand Staircase, only slightly smaller, less ornate and spanning less floors.

It only spanned three decks (A Deck to C Deck), but it gave access to the First Class Smoke Room, First Class Promenade, and First Class Lounge (A Deck landing), the Café Parisien (B Deck landing) and First Class cabins (B and C Deck landings).
