The Canaries have worked hard to re-sign most of the squad that helped them clinch the Championship title last season.
One of them was midfielder Trybull, who has extended his deal until 2022.
Speaking to canaries.co.uk, Trybull said: "I'm feeling very good and happy to sign a new deal, I really like living here and I love to play for this special Club as there are so many positive things about Norwich.
"When I first came to the Club, it was all very new to me and my wife as it was a new country and a different experience.
"But my teammates made it easy for me to fit in the squad and the supporters have helped me and my family to feel comfortable in the city and stadium so it was clear to us that we wanted to stay.
"The Club and especially the Head Coach [Farke] and Stuart [Webber] have given me so much and I just want to give back to them."
