The sport of Fencing was initiated at The Royal College in 1914 on a small scale, with six boys who could afford it. But due to the dangerous nature of the sport and the lack of protective gear back in the day, Principal Mr. Charles Hartley put a stop to the short-lived sport.

Efforts by the National Association of Fencing reintroduced the sport to the College in 2014. Since then, glory has followed as the Royal College fencing team emerged champions at the Sri Lanka Junior National Fencing Championship in the past year. They were the runners-up in 2017 and 2018.
