Rowing at the 1900 Summer Olympics – Men's coxed four

Initially, the top boat in each semifinal plus the runner-up in the third semifinal (which had four boats instead of the three boats competing in each of the other two), were to advance. Following protests which ensued after the runner-up in the second semifinal and the third-place boat in the third semifinal each posted better times than the winner of the first, the qualification rules for the final were altered. Eventually, the six boats were broken into two groups and competed in separate finals. The runners-up in semifinals 2 and 3 as well as the third-place boat in semifinal 3 competed in the first final, while the three semifinal winners competed in the second.
