'Queer Eye' Alum Tom Jackson Dead of Cancer at 63

"Queer Eye" alum Tom Jackson, who appeared on the show's first season, has died of cancer ... and now fans are down a former hero.

According to his obituary, Tom died on March 3 at 11:49 PM ... after succumbing to stage 4 adenocarcinoma -- a glandular cancer, which doctors said had metastasized.

The show's official website shared the sad news Wednesday on Instagram, posting ... "It's with a heavy heart that we say goodbye to a member of our Queer Eye family. Rest in peace, Tom Jackson"

Fans will best remember Tom from season 1 of the Netflix reboot. He became a fan favorite after appearing in the premiere episode in 2018 alongside the Fab Five. He once dropped the iconic line, "You can't fix ugly."

Before his reality TV stardom he reportedly worked as a dump-truck driver in Georgia ... after he'd retired from FedEx.

Tom is survived by his 2 grandsons, 2 sisters and his daughter, who also appeared on the series.

His family said in a statement, "We will never forget our beloved Tom. He brought joy, humor, persistence, and love to our family. He is special to us, and we look forward to seeing him again one day."

They're also suggesting fans watch his episode of "Queer Eye" in his honor.

Tom was 63.
