The singer and partner Kristina Rihanoff exited the competition after polling the fewest public votes, leaving Harry Judd and Chelsee Healey to battle for victory in the grand final.
The pair received a standing from the audience and judges as they congratulated their competitors on making the final two.
"This has been the most incredible experience, other than my children and my wife of course, in my life," Donovan said. "I want to thank the public for voting for us, we've come so far.
"I want to thank my family, my wife and my two kids. I might get emotional here but they have been here through the ups and down.
"To Kristina, who has been so patient, who has remained focused, who has one of the most incredible talents and visions to tell a story, she has done me proud."
Digital Spy readers predicted that Donovan would finish in third place, tipping Harry Judd to be the winner of Strictly Come Dancing.
Donovan recently claimed that the BBC One dancing competition had beat The X Factor in the ratings because of this year's strong casting.
