The Rugby Union club, Leeds St John's formed in 1870, however in 1895, when many teams broke off to form Rugby League, the club also switched codes. The club played as Leeds RLFC until 1995, when they changed their name to 'Leeds Rhinos'. This was done to mark the start of the Superleague. Many other clubs made similar name changes. Leeds Rhinos have won the Superleague in 2004, 2007, 2008 and 2009.
Leeds Rhinos play at the Headingley Carnegie Stadium, which has both Rugby and Cricket grounds. The rugby stadium has a capacity of 22,500. The stadium is located in the Headingley district of the city and is near both Headingley and Burley Park railway stations.
The club mascot is Ronnie the Rhino, who was introduced when the club changed names. As well as making appearances at the stadium on match days, Ronnie also travels around schools in Leeds promoting sport and healthy living. Ronnie has been popular with children who attend games, emphasizing the club's intention to cater for families.
