The ATCO World Series Finals will return to The Queen's Club in London for the third time next year, from 4-8 January.
The flagship PSA event, which celebrates its 18th staging since 1993, will feature the top eight players from the 2011 Dunlop PSA World Series Standings following their achievements in this year's nine PSA World Series events (two of which have yet to be completed).
But new for 2012 will be the simultaneous staging of the WISPA World Series Finals - featuring the top eight women in the now-completed 2011 WISPA World Series programme, led by Malaysia's record six-time world champion Nicol David.
The women's event, launched in 1998, has not been staged since 2004 - and never before in England. It will be run alongside the men's championship for the first time.
Nick Matthew, the men's world number one and world champion from England who currently leads this year's PSA World Series Standings, said: "The ATCO World Series Finals are a culmination of a year's hard work and graft on tour and you truly have to earn the right to be amongst the eight players in the finals.
"Queen's has proved to be an amazing venue for the last couple of years and it would be a great honour to become Tour champion in this iconic British venue."
Nicol David added: "This is such an important event for women's squash as the top eight women are going to be joining with the top eight men in the ATCO World Series Finals. We have been playing hard all year around the world and it will be great to come together with the men to fight for this title, especially somewhere as well known as the Queen's Club and where our association is now based.
"I'm very glad to be part of this event for the first time and looking forward to a spectacular event in London."
