Messi captained Argentina, scored seven times and won the Golden Ball as his country won the 2022 World Cup in Qatar in December.
He is the first athlete to win the team and individual awards in the same year.
Sportswoman of the Year went to Jamaican sprinter Shelly-Ann Fraser-Pryce.
She won the women’s 100m world title at the World Athletics Championships in Oregon in July, becoming the first person to win five golds in an individual track event at the championships.
“This is a special honour,” said PSG forward Messi, 35. “Particularly as the Laureus World Sports Awards are in Paris this year, the city that has welcomed my family since we came here in 2021.
“I want to thank all my team-mates, not only from the national team but also at PSG – I have achieved none of this alone and I am grateful to be able to share everything with them.”
Fraser-Pryce’s 100m gold came 13 years after her first and the 36-year-old has more world sprint titles than any other athlete.
She ran a sub-10.7-seconds 100m seven times in 2022, three more than the previous best for a female sprinter in a calendar year.
“I was thrilled to be nominated alongside such inspiring women athletes, and to win this award, voted for by some of the greatest sportsmen and women of all time, is just amazing,” she said.
Argentina lifted the World Cup for the third time, beating France in a penalty shootout in Doha after possibly the greatest final of all time, which ended in a 3-3 draw.
They beat England’s Euro 2022-winning Lionesses, men’s Champions League winners Real Madrid and France’s men’s Six Nations champions to win the award.
Manchester United and Denmark midfielder Christian Eriksen won Comeback of the Year following his return to football after collapsing on the pitch because of cardiac arrest during Euro 2020, while men’s tennis world number two Carlos Alcaraz was awarded World Breakthrough of the Year after a 2022 in which the then 19-year-old won the US Open and became tennis’ youngest men’s number one.ٌ
