The 23-year-old left Villa in the summer to join Millwall on a permanent deal having made just three substitute appearances for the Barclays Premier League side.
Lowry will get the chance to show his old club what they are missing when Villa arrive at The Den at the end of the month.
"Obviously I've got many friends at Villa, including Nathan Baker, who was here at Millwall for a spell too, and I'll be looking forward to seeing them again," he told the Lions' website.
"More than that, though, it's a great draw for us as a club, exciting for the fans and we'll be hoping for a bit of a giantkilling."
