The striker helped Norwich return to the Premier League last season.
Jordan Hugill has joined West Brom on a season-long loan from Norwich.
The former Preston and West Ham striker joined the Canaries ahead of the 2020-21 season and scored five goals as they were promoted back to the top flight.
He will now look to achieve the same as West Brom target an immediate return to the Premier League and manager Valerien Ismael believes the 29-year-old is the ideal striker for his side.
“We took our time to make the right decision and, after our first discussion with Jordan, we felt that he’s the right player for us,” Ismael told the club website.
“He was immediately committed to Albion and to our way to work and play. It’s exactly what we wanted; for a player to want to come here to help make us successful. I also think this is the right place for him.
“I think with his experience, his mentality and his work ethic, he will suit us perfectly.”
