At the time of the Czechoslovak First League, SK Kladno has spent most of its history in the top division, but from 2011, it plays in amateur tiers.

On 15 February 1903, a group of young men sitting in the former "U Českého dvora" Hotel in Kladno decided to establish their own sports club, at which they "cultivated" the new game of the time – football.

Among them were Otakar Škvain-Mazal (1894–1941), a pupil of SK Kladno and the author of three goals at the Antwerp Olympics in 1920 where the Czechoslovak national team made it to the final.

Jan Fábera (1928–1984), a player SK Kladno, who successfully trained the national team of Sudan and was active as a coach in Algeria and Iceland.

Josef Kadraba (born 1933), a Kladno striker and a player and coach for Slovan Wien, but mostly a member of the Czechoslovak national team, which surprised many by achieving the silver medal at the 1962 FIFA World Cup in Chile.

It should also be recalled that the legendary Czech striker and long-time player at Slavia Praha, Josef Bican (1913–2001), trained the Kladno first team in the 1962–63 season.
