Ruch Radzionków is a Polish association football club based in Radzionków. As of the 2024-2025 season the club compete in the IV liga Silesia.

The club was established by a group of Polish activists who modelled the organisation on contemporary German sports associations. Founded as Towarzystwo Gier i Zabaw (Games and Entertainment Society) on the 14 August 1919, the First Silesian Uprising broke out just a few days later in which members of the newly created club became involved. The following year the club changed its name to Ruch Radzionków, although the prefix ruch (lit. movement) was not as unambiguously Polish as Piast, Radzin, and Jastrząb which were also contenders for the club’s name.

During the first few decades of its existence Ruch Radzionków contested a series of international matches, of which little is known, and were able to build a stadium which was completed in 1933. In 1935 a Sanation-backed contender to the club was established named Strzelec Radzionków. The state-initiated club was intended to absorb Ruch Radzionków, with the latter being evicted from their newly built ground. However, Strzelec Radzionków failed to gain public support and Ruch Radzionków were able to return to their ground.

In early to mid 1950s the club first met Piast Gliwice in the regional league. In 1956 Ruch were listed in the Trzecia liga (third league) group named Stalinogrodzka liga wojewódzka, id est the Stalinogród regional league, playing under the name ZKS Górnik Radzionków between 1953-55. The 1950s saw the club gain promotion out of the regional leagues into the national II liga for the first time.

The 1990s were an era of success for Ruch Radzionków in which they reached the quarter finals of the Polish Cup and had been promoted to the I liga by the end of the decade. During their first season in the top flight the club won a surprising string of victories including a 5-0 defeat over Widzew Łódź in their first match, a 4-0 victory over title holders ŁKS Łódź, an historic draw with Wisła Kraków, and a 4-1 defeat over Lech Poznań thereby finishing their opponents hopes of winning the league. The club remained in the top tier for a further 3 seasons.

In 2012 Ruch Radzionków was disaffiliated due to financial problems, and the club board decided to withdraw from the I liga following the 2011–12 season.

The club were champions of the Silesia I group of IV liga in the 2017–18 season and won the play-offs against Polonia Bytom, giving them promotion to the III liga.

Ruch Radzionków moved into their first purpose built stadium in 1933. The construction of the ground was patronised by the voivode of the Silesian Voivodeship Michał Grażyński, for whom the ground was subsequently named. Michał Grażyński Stadium was considered state-of-the-art at the time, being the second biggest in Poland after Ruch Chorzów Stadium.

Ruch Radzionków have a strong Silesian identity in contrast to nearby rivals Polonia Bytom who are associated with a Polish one due to their historic links with the club Pogoń Lwów. During their first spell in the top tier Ruch Radzionków‘s ground was located in the Stroszek district of Bytom, an added symbolism to their success.

Due to the history of cider production and consumption in Radzionków, inhabitants of the town are known as cidry. Fans of Ruch Radzionków have adopted the moniker as their club’s nickname. Since 2009 the fanzine Ciderland has been produced, which is distributed within the town and wider areas such as Bytom, Tarnowskie Góry, Orzech and Świerklaniec, from where the club draw their support. The club’s anthem Ciderland is sung by fans during matches;
