Brighton and Hove Albion appoint former Norwich and Newcastle boss
The former Newcastle, Birmingham and Norwich boss, 56, will take charge of his first game in Saturday's FA Cup third-round tie at Brentford and replaces Sammy Hypia who left earlier this month with Brighton verging on the relegation spots.
Hughton who was sacked by Norwich has a solid track record and has experience in both the Championship and Premier League.
The former Tottenham, West Ham, Brentford and Republic of Ireland full-back was assistant manager at Spurs before joining Kevin Keegan's coaching staff on Tyneside.
He became caretaker boss when Keegan left St James' Park in 2008 and took the job on a full-time basis the following year.
Hughton led the Magpies to promotion from the Championship in 2010, but was controversially sacked in December of that year with the side 11th in the Premier League.
He guided Birmingham to the Championship play-offs in 2011-12 before moving on to Norwich, but was sacked with five games remaining last season, which ended with the club being relegated.
Seagulls chairman Tony Bloom told the club website: "Chris has an excellent record in coaching and management.
"Chris is also a manager who has a track record for developing talent at all levels from academy upwards and will embrace the work we've been doing at the club in this area in recent seasons.
"Importantly, we also felt Chris is someone who can improve our immediate situation, while also having the management credentials and skills to plan our long-term future and help us to get back to progressing in the way we have in previous seasons."
Since Hyypia's departure, Brighton have picked up four points in two games under caretaker manager Nathan Jones.
Hughton had previously said he was interested in the vacant post at Brighton, as well as West Brom, having ruled out a return to former club Newcastle.
"It's a very good club and one that has a tremendous infrastructure," he told BBC Radio 4.
"Anybody like myself that has been out for a while would be interested in that type of job."
Brighton, meanwhile, finished in the Championship play-offs in the last two seasons, but struggled this term under Hyypia, who was appointed in the summer, two months after being sacked by German club Bayer Leverkusen.
