The Saskatchewan Roughriders are a football team. They were founded as the Regina Rugby Club in 1910, adopting the Roughrider nickname in 1924. Until 1936 they were the West's dominant team, winning the western title 15 of the first 21 years. On the national scene, however, it was 1966 before they won their first Grey Cup. Although defeated in their 7 early Grey Cup attempts (1923, 1928-32, 1934), the Roughriders won respect for western football, introducing the forward pass to the Grey Cup in 1929 and scoring the West's first Grey Cup touchdown in 1930.

In 1948, the name was changed to Saskatchewan Roughriders to indicate that it was the province's team rather than from any one centre. It was also the year when the uniforms changed to green and white, a modification that was made for practical reasons: an executive with the team, Jack Fyffe, happened to be in Chicago and found two complete sets of green and white nylon jerseys on sale in a surplus store. The colours green and white remain to this day.

Except for a 1951 Cup loss to Ottawa, they did not return to the national final until the 1960s. In 1956 tragedy struck the team when 4 players were killed in a plane crash when returning from the All-Star Game in Vancouver. A rebuilding program began in 1962 and the team made the playoffs in each of the next 15 years.

Led by quarterback Ron Lancaster and indomitable running back George Reed, the team made 5 Grey Cup appearances (1966, 1967, 1969, 1972, 1976) - its sole victory occurring over Ottawa in 1966. Strong fan support allowed the community-owned team to survive a string of 11 consecutive years without making the playoffs (1977-87).

The team rebounded to advance to the Grey Cup game in 1989, defeating Hamilton in one of the most exciting games in Cup history. In 1997 Saskatchewan returned to the Grey Cup to face the defending Grey Cup champions, the Toronto Argonauts. They were no match for the heavily favoured Argos, losing 47-23. However, their next Grey Cup appearance, in 2007, resulted in a win against the Winnipeg Blue Bombers with a score of 23-19.

The team's most disappointing loss in recent memory came in 2009 when the Montreal Alouettes came from behind in the last 10 minutes of the game to win by one point. In the final play the Alouette's Damon Duval kicked a last-second field goal on a second attempt after the Roughriders had been penalized for having too many men on the field. The goal gave the Alouettes a one-point lead, allowing them to beat out the Roughriders and clinch the game 28-27. They played the Alouettes again in 2010, but lost with a score of 21-18.

The Roughriders play their home games at Mosaic Stadium at Taylor Field in Regina, an outdoor stadium that seats 30 945.
