The Argentine World Cup-winning captain is in the state for Wednesday's inauguration of a new showroom of Boby Chemmanur International Jewellers and Airlines, for which he is the brand ambassador.
On a two-day trip to the state, Maradona arrived by a chartered helicopter from Nedumabassery International airport at Kochi.
Tight security was in place in the city, which saw a festive atmosphere with hundreds of fans pouring in from Kozhikode, Malappuram and Kasargod districts.
About 2000 police personnel were enlisted for security.
Maradona, who led Argentina to a World Cup triumph in 1986, waved to the crowds after landing at Kannur, which has hosted many international and national soccer tournaments.
