Richard Sylvannus Reynolds (20 June 1915 – 2 September 2002) was an Australian rules footballer who played for the Essendon Football Club in the Victorian Football League (VFL).

Reynolds is one of four footballers to have won three Brownlow Medals, with the others being Haydn Bunton Sr., Bob Skilton and Ian Stewart. Revered by Essendon supporters, he was often referred to simply as "King Richard".

The son of William Meader Reynolds (1886–1940) and Mary James Reynolds, née Thompson (1885–1941), and one of seven children, Richard Sylvannus Reynolds was born on 20 June 1915. He died on 2 September 2002. He was the brother of Tom Reynolds, the cousin of Richmond champion player and coach Max Oppy, and the grandfather of Joel Reynolds.

Reynolds grew up supporting Carlton and sold lollies outside Princes Park on match days.

When Reynolds won his first Brownlow Medal in 1934, Fitzroy champion Haydn Bunton Sr., whom Reynolds had narrowly beaten to win the award, was the first person to telegraph his congratulations, a sporting gesture that Reynolds deeply appreciated.

Reynolds would normally wear the number three guernsey throughout his playing career with Essendon, but had to wear the number four guernsey during one match of the 1937 VFL season when he left his uniform at home.

In July 1944 Reynolds surpassed Billy Griffith club record of 187 games.

In June 1947, it was announced that Reynolds would start writing about football for the now-defunct Melbourne newspaper The Argus.
