Obano has put pen to paper to commit his future with Bath after emerging from the West Country side's Academy.
The 23-year-old has been shown favour by England boss Eddie Jones this season after enjoying a breakthrough campaign with Bath.
The powerful young loosehead has become one of the hardest hitting forwards in the Premiership whilst also drastically improving his work-rate and fitness since the beginning of the season.
Obano is currently in contention for a ticket to South Africa for England's three-test series against the Springboks this June and could earn his Test debut over the summer.
The London-born prop has made 50 appearances to date in the Blue, Black and White after making his debut against Ospreys in the Anglo-Welsh Cup in 2015.
Commenting on the news of his contract extension earlier today, Obano said: “I’ve really enjoyed my rugby this year. Undoubtedly we would have liked to have finished higher, but the Club is ambitious and I anticipate great things will follow. We will continue to work hard and hopefully we will reap what we sow.
“I’ve got to give big credit to the coaches, S&C and physios for investing so much time in me, and hopefully I’ve gone some way to acknowledging that support.”
Director of Rugby, Todd Blackadder, added: “Beno is a huge character, who will play a significant role in the Club’s future. He has delivered performance after performance throughout this season, and with the fact he’s only 23, he can only get better. As with Toby (Faletau), Beno is part of the core group of players committing to the Club and who we will build the long-term future around, which is really exciting.
“Beno sets high standards for himself, and it’s his attention to his craft which will see him go on to achieve big things for Bath and England when the opportunity comes around.”
