Man of the tournament Sachin Tendulkar took top spot, moving up 11 places, after scoring 673 runs during India's march to the final.
And four India bowlers featured in the top 15, with Javagal Srinath highest placed at 10.
The previous leading batsman Matthew Hayden dropped to sixth after a quiet tournament.
He was topped by Ricky Ponting, who moved up to fourth after his record 140 in the final.
Adam Gilchrist is just behind his captain while Andrew Symonds was one of the most improved players of the World Cup, moving up 44 places to 29th.
Despite his 22 World Cup wickets, Brett Lee drops a place in the bowlers rating to third, passed by the only man to take more wickets in the tournament, Sri Lanka's Chaminda Vaas.
Team-mate Glenn McGrath moves up to second place.
But South Africa's Shaun Pollock retains top spot despite the host nation's failure to get past the first round of the tournament.
ICC TEAM RANKINGS
Meanwhile, Australia have extended their lead at the top of the official one-day international rankings.
But South Africa are still in second spot in the table, maintained by the International Cricket Council (ICC).
The table gives weighting to recent matches and takes into account strength of opponent, but gives no extra credence to World Cup games.
Beaten finalists India remain in fifth place, but they have closed on Sri Lanka and Pakistan to move within striking distance of third spot.
