The 23-year-old joins the Men of Gwent from English Gallagher Premiership outfit Leicester Tigers and has linked up with the squad with immediate effect.
Dean Ryan, Director of Dragons Rugby, said: “We believe that Jordan can not only continue his development but also contribute to our environment and we would like to thank Leicester for working with us on this occasion.
“He is a different option for us in the back three and we all look forward to working with him.”
Olowofela came through the Tigers Academy and the wing has gone on to make 41 appearances and spent the 2020/2021 season on loan with the Western Force in Australia, making 10 appearances.
The former England U20 international is sure to excite Dragons fans with his high-speed attacking style.
Olowofela said: “I would like to thank Leicester and the Dragons for their support of me to come here this season.
“It’s a great opportunity for me to develop my game further and I can‘t wait to get started and wear that Dragons jersey.”
