The Baggies parted company with Roberto Di Matteo at the weekend following a run of 13 defeats in 18 games in all competitions, and have quickly moved to appoint former Liverpool boss Hodgson, who left Anfield last month after little over six months in charge.
A statement on the club’s official website read: “West Bromwich Albion are delighted to announce they have appointed Roy Hodgson as the club's new head coach.
“The 63-year-old former Inter Milan, Switzerland, Fulham and Liverpool boss has this morning committed himself to the club until June 2012.
“Michael Appleton, who was appointed caretaker head coach on Sunday after Roberto Di Matteo was relieved of his duties, will remain in charge for the West Ham game (on Saturday).”
