Media reports said last week the show had not been renewed for a seventh season, but Allen did not publicly comment until Tuesday when the network announced its 2017-18 schedule and "Last Man Standing" wasn't on it.
"Stunned and blindsided by the network I called home for the last six years. #lastmanstanding," Allen tweeted.
The series is about a conservative, church-going Colorado man who is married with three adult daughters and in charge of marketing for a chain of outdoor, sporting-goods outlets.
"We didn't design it like this, like we are different from everybody else, but 'Last Man Standing,' in syndication now, it can go anywhere. It can be at 6 o'clock. It's family friendly. We're not holier than thou who did it this way, but it is a very different situation when you have a show that the whole family can watch together," Allen told UPI in a phone interview last year.
"And I really like that we're doing this."
A change.org petition to save the series has been signed by nearly 120,000 people.
