The Internacional Foot-ball Club was a football team based in Madrid, Spain, which existed only in 1903.

Its predecessor was the New Foot-Ball Club, disappearing just three months later when it merged with Moderno-Madrid FC (now Real Madrid).

[4] The club's first Board of Directors was made up as follows: President, Tomás Guyarro; Vice President, Tomás Moore; Secretary, Eugenio Bisbal; Treasurer, Pío Wandoseil; Members: George Graig, Eugenio Vallarino, Angel Garrido, D. E. Valenti and Luis Romero de Tejada.

[4] Due to the limited extension of said sport in the country, there were still no proper or properly formed venues for its practice, so this group of football pioneers was distributed by different vacant lots and areas of the city in which the players themselves arrived early to paint the lines of the field and prepare the goals to be able to play their matches.

It was one of the reasons for the instability and disappearance suffered by many clubs at the time, where progress seemed like a feat.
