Daijiro Kato (加藤大治郎, Katō Daijirō, July 4, 1976 – April 20, 2003) was a Japanese Grand Prix motorcycle road racer, the 2001 250cc world champion, and the 2000 and 2002 Suzuka 8 Hours winner. He died as a result of injuries sustained during a crash at Suzuka race circuit, Japan.

Kato was born in Saitama, and started racing miniature bikes at an early age, becoming a four-time national champion in the Japanese pocket-bike championship.

He began road racing in 1992, and entered his first Grand Prix in 1996, as a wild-card rider. In the 250cc class, Kato finished third after debuting at his home circuit of Suzuka Circuit. The next year, he won the Japanese Championship, and again entered the Japanese Grand Prix with a wild card, winning the race at this occasion.

In spite of these successes, Kato did not ride his first full Grand Prix season until 2000, when he started in the 250cc, riding a Honda. He won four races that season (of which two in Japan), and placed third in the championship. In 2001, he dominated the 250cc championship. He won no fewer than 11 races, a record in 250cc, and easily won the title. In that season he set a new record for the most points in a single season in 250cc class with 322 points.

The following season, Kato moved up to the MotoGP class (formerly 500cc) racing for Honda Racing Corporation (HRC) in the Fortuna Gresini Racing team. Some strong performances on the Honda NSR500 two-stroke bike in the first half of the season including second place at the 2002 Spanish motorcycle Grand Prix at Jerez circuit, meant he was given a full factory supported four-stroke Honda RC211V for the rest of the season; his best result on the RC211V was a second place at the Czech Grand Prix at Brno.
