The club was established in 1905 with the name Sporting Gijonés, Anselmo López being the first president. King Alfonso XIII accepted the Royal patronage of the club for the Spanish crown in 1912, introducing the term “Real” (Spanish for “Royal”) to its name, becoming Real Sporting Club Gijonés. In 1916 a new change took place to adopt today’s denomination, Real Sporting de Gijón. From 1941 until the 1970s, due to a temporary law forbidding the use of foreign words in football club names, the team’s official denomination was Real Gijón.

In 1944, the club was promoted into First Division for the first time, and played thereafter in both the first and second divisions, achieving greatest success in the late 1970s and early 1980s, competing for league and national cup titles and laying the groundwork for a 21-year continuous stretch in La Liga. During this period, Sporting competed in the UEFA Cup six times, losing in the Round of 32 four times, and the Round of 16 twice, most recently in 1991-92.
