Allen, who held the Melbourne seat of Higgins from 2019 until 2022, revealed earlier this year that she had been diagnosed with a rare form of cancer.
"It is with a heavy heart that we announce the passing of our beloved Katie (Mum)," a post on the former MP's Facebook page tonight.

"She spent her life caring for others as a mother, doctor, professor, MP and friend.
"She is deeply loved.
"She passed in peace surrounded by family and lived a full, beautiful life, all the way to the end.
"We love you so much."
Allen shared in May that she had been diagnosed with stage 4 cholangiocarcinoma that had already spread.
She spoke at the time about feeling "immense gratitude for the life I've led".
"I'm surrounded by love - my family, my friends, my community. I've been fortunate to serve both as a doctor and in public life, always with the hope of making things better for others," she said.
Prime Minister Anthony Albanese led tributes for Allen, sending his "heartfelt condolences" to her family and friends.
"Katie believed deeply in serving her community, her nation and her fellow Australians. She dedicated her life, her talents and her courage to making our nation a better place. May she rest in eternal peace," Albanese said.
Former treasurer Josh Frydenberg described his former colleague as "wonderful".
"Deeply saddened by the passing of our good friend Katie Allen," he said.
"Brave, bright and beautiful, Katie was special, a cut above the rest.

"Later it would be a privilege to be Parliamentary neighbours in adjoining electorates.
"She was a wonderful, hard working local member for Higgins and a big contributor in Canberra, where her deep care for others drove every position she took.
"She was principled and strong, always determined to make a difference, and she did. She will be hugely missed.
"Sending all our love to Malcolm, Monty, Jemima, Arabella and Archie."
