Steve Tandy and Gruff Rees have signed new long-term contracts to remain at the Ospreys.
Head coach Tandy has been rewarded with a four-year contract, while backs coach Rees has committed to the club until 2015.
The duo, who were appointed in February 2012, guided the club to the RaboDirect PRO12 title in their first season, while they are in fifth place this time around.
Andrew Hore, chief operations officer at the Ospreys, told the club's official site: "Steve and Gruff are two of the brightest, most exciting young coaches around and have already developed excellent reputations as innovative, forward thinkers.
"Products of the well established coach development pathway we have in place here at the Ospreys, they have both worked extremely hard to help put foundations in place over the last 15 months to help ensure a sustainable, long term future for the region.
"They have had to face up to a number of challenges but have tackled them head on in a typically forthright manner, not shirking the tough decisions, and whatever happens in the PRO12 this weekend we are now in a strong position to kick-on for next season and beyond.
"We are obviously delighted that they see themselves as part of the future of the Ospreys, a cause they both care passionately for, and they have a desire to finish off the job they've started.
"Steve is a true stalwart of the region having served us so well as a player, and is a straight talker and natural leader. Having worked as a Development Officer for Bridgend and within our age grade system he has a real understanding of where our talent comes from.
"Gruff has a passion for skills development which is essential to our future as we look to continue bringing through young talent to represent the region."
