Hello Kitty is 51 years old as of 2025, since her official birthday is November 1, 1974.

How we get that age

  • Hello Kitty (full name Kitty White) was created in 1974 by illustrator Yuko Shimizu for Sanrio.
  • Her official in‑universe birthday is November 1, 1974.
  • That means:
    • She turned 50 on November 1, 2024 (her golden anniversary, widely celebrated in 2024).
* She is 51 during most of 2025, and will turn 52 on November 1, 2026.

So if someone asks “how old is Hello Kitty?” today in a general sense, the clearest answer is that she’s a little over 50 years old, specifically 51 in 2025, counting from her canonical 1974 birthday.
