The decision was taken by King Mohammed at a meeting on Monday attended by Youth and Sports Minister Ahmed Moussaoui and top sports officials.
Morocco made bids to host the World Cup finals in 1994, 1998 and 2006, but the tournaments were awarded by soccer's world governing body FIFA to the United States, France and Germany.
The North African country's failures were blamed on poor infrastructure. For its last failed attempt, Morocco said it planned to invest over $500m to build new stadiums.
FIFA president Sepp Blatter said last month Africa would "definitely" host the 2010 World Cup.
South Africa, narrowly and controversially beaten by Germany in the vote for the 2006 tournament, confirmed in March that it would mount its second bid for the finals.
Egypt, Nigeria and Tunisia have also expressed an interest in hosting the tournament in nine years' time.
The Royal Palace statement said the king "reiterated his confidence in Driss Benhima, appointing him vice-chairman of the national committee in charge of the Moroccan bid for the World Cup."
Benhima, who also heads state-run power utility ONE, led Morroco's efforts to stage the 2006 tournament.
The monarch ordered the building of all necessary sports infrastructure ?gas soon as possible", the statement added.
