As of my last update in April 2023, Katharine Hepburn held the record for the most Oscars won for Best Actress. She won four Academy Awards for Best Actress over the course of her illustrious career. Hepburn's Oscars were for her roles in the following films:

1. "Morning Glory" (1933)
2. "Guess Who's Coming to Dinner" (1967)
3. "The Lion in Winter" (1968)
4. "On Golden Pond" (1981)

Katharine Hepburn's record is particularly notable because she won these awards over a span of nearly 50 years, demonstrating her enduring talent and versatility as an actress. Her career in Hollywood spanned several decades, and she remains one of the most celebrated actresses in the history of American cinema.<end_of_turn><eos>
