The 1965 Motocross World Championship was the 9th edition of the Motocross World Championship organized by the FIM and reserved for 500cc and 250cc motorcycles.

Summary Jeff Smith won his second consecutive 500cc motocross world championship for the BSA factory racing team with six Grand Prix victories. Paul Friedrichs took three victories to claim second place for the ČZ factory, ahead of former world champion Rolf Tibblin.

Before the 500cc championship opening round even began, former World Champions Rolf Tibblin and Bill Nilsson were involved in a serious accident while preparing for the race. Tibblin and Nilsson were test-riding motorcycles in their hotel parking lot when they collided in a blind corner. Neither rider was wearing their protective riding apparel, and Nilsson suffered a broken arm, an amputated toe, and a concussion, while Tibblin lost the end of his little finger and also received a concussion, which forced him to sit out the start of the season.

Smith's win riding a BSA Victor marked the last time that a four-stroke engine powered motorcycle would win the 500cc motocross world championship for the next several decades, as two-stroke engine technology began to dominate off-road motorcycle racing until 2003, when mounting government environmental regulations caused the FIM to implement new rules favoring environmentally friendlier four-stroke engines. Defending 250cc World Champion Joël Robert was invited by the ČZ factory to compete in the 500cc Czechoslovak Grand Prix during a break in the 250cc World Championship schedule. Robert was leading the first heat race when his motorcycle experienced a mechanical failure, before rebounding to win the second heat race in a rare 500cc class appearance.

In the 250cc division, Russian ČZ rider Victor Arbekov claimed the world championship ahead of the defending champion, Joël Robert. Robert was considered the fastest motocross racer in the world at the time but his lackadaisical attitude towards physical fitness training and voracious appetite for the good life meant that he didn't always live up to expectations. Although Robert won three Grand Prix races in 1965, his World Championship title defense was marred by crashes, mechanical failures and minor injuries. Torsten Hallman was completing his senior year in college in 1965 and the heavy workload meant he had to reduce his racing schedule. Arbekov filled the void left by his two main rivals by winning five Grand Prix races, securing the 1965 World Championship ahead of his nearest challenger, Robert, at the penultimate round in Sweden. Future five-time World Champion Roger De Coster made his first World Championship appearance at the 250cc French Grand Prix. The Suzuki factory became the first Japanese manufacturer to compete in a motocross world championship event, with riders Kazuo Kubo and Matsuhisa Kojima entering the 250cc Swedish Grand Prix on 25 July.
