Toyosi Olusanya has signed a two-year deal following the expiry of his contract with Major League Soccer side Houston Dynamo.
The 28-year-old becomes Aberdeen's fifth addition of the summer and returns to Pittodrie after a successful loan spell during the second half of last season.
Having arrived in January, the striker quickly became a popular figure within the dressing room and amongst the Red Army, making 18 appearances and contributing important goals and assists as the Dons finished the campaign strongly.
A product of the AFC Wimbledon academy, Toyosi has also enjoyed spells with Middlesbrough, St Mirren, Arbroath and Doncaster Rovers before making the move to Houston Dynamo in 2025.
Now reunited with manager Stephen Robinson, the powerful forward is excited to continue his Aberdeen journey.
Speaking after securing the deal, Stephen Robinson said: "Toyosi made a really positive impact during his time with us last season and we're delighted to bring him back to the Club.
"He gives us something different in the final third. His pace, power and energy make him a difficult opponent for defenders, while his work ethic and attitude are exactly what we want within the group.
"Having already spent six months here, he understands the expectations that come with representing Aberdeen Football Club and we believe there is much more to come from him. We're looking forward to helping him continue his development and seeing the contribution he can make over the next two years."
After putting pen to paper, Toyosi spoke to RedTV and admitted returning to Pittodrie was an easy decision.
"I am buzzing to be back," he said.
"From the moment I arrived in January, I felt welcomed by everyone at the Club. The staff, the players and the supporters all made me feel at home.
"Coming in during the middle of a season isn't always easy. I was still working my way back to full fitness and adapting to a new environment, but I felt I improved as the weeks went on and now I have the opportunity to start again with a full pre-season behind me.
"I know the manager well and I know exactly what he expects from me. That gives me a great platform to push on and show what I can do.
"Most importantly, I loved my time at Aberdeen. I enjoy living in the city, I understand what the Club means to people and I experienced first-hand the incredible backing we receive from the supporters.
"When you play for Aberdeen, there is an expectation to compete, win matches and challenge at the top end of the table and for trophies. That's what attracted me back and I'm determined to play my part in delivering success for the Club."
Toyosi will link up with his teammates later this week as preparations for the 2026/27 campaign get underway.
Everyone at Aberdeen Football Club is delighted to welcome Toyosi back to Pittodrie and wishes him every success during his time in Red.
