As of August 2025, there are six Apollo astronauts still alive. These include four who walked on the Moon: Buzz Aldrin (Apollo 11), David Scott (Apollo 9 and 15), Charles Duke (Apollo 16), and Harrison Schmitt (Apollo 17). Additionally, two astronauts who flew to the Moon but did not land are Russell Schweickart (Apollo 9) and Fred Haise (Apollo 13). However, it is notable that James "Jim" Lovell, an Apollo 8 and 13 astronaut, died on August 7, 2025, reducing the number of living Apollo astronauts who flew to the Moon.
So the correct count, considering Jim Lovell's recent passing, is six living Apollo astronauts as of August 2025.
