Como 1907 was founded on 25 May 1907 in Como, a lakeside city in the Lombardy region of northern Italy. The club adopted royal blue as its colours and has called Stadio Giuseppe Sinigaglia — opened in 1927 and sitting on the shores of Lake Como — its home ever since.
The club's early decades were marked by genuine ambition. A dominant 1930–31 Prima Divisione campaign, in which Como went unbeaten across the regular season and play-offs while scoring 90 goals in 32 matches, brought promotion to Serie B. By 1949 the club had climbed to Serie A for the first time, and their most memorable spell in the top flight came in 1984–89, when a five-season run in Serie A included back-to-back ninth-place finishes in 1986 and 1987. Notable honours along the way include the 1927 Coppa Volta and the 1996–97 Coppa Italia Serie C.
Financial turbulence defined the 2000s. A bankruptcy declaration in 2004 saw the club excluded from professional football and re-entered at Serie D level, and a second bankruptcy in 2016 forced another refoundation. Recovery accelerated dramatically after Indonesian conglomerate Djarum Group, led by brothers Robert Budi Hartono and Michael Bambang Hartono, acquired the club in 2019. Player-turned-coach Cesc Fàbregas, who holds a minority stake alongside fellow minority shareholder Thierry Henry, guided the club to second place in Serie B in 2023–24, securing promotion back to Serie A after a 21-year absence. Como finished their first season back in the top flight in tenth place.
