Edgard Colle (18 May 1897 – 19 April 1932) was a Belgian chess master. He scored excellent results in major international tournaments, including first at Amsterdam 1926, ahead of Savielly Tartakower and future world champion Max Euwe; first at Meran 1926, in a strong field ahead of Esteban Canal; and won twice outright at Scarborough in 1927, and again in 1930, ahead of Maróczy and Rubinstein.

Colle is remembered today primarily for his introduction of the chess opening now known as the Colle System: 1.d4 d5 2.Nf3 Nf6 3.e3. White normally follows up with Bd3, 0-0, and Nbd2, playing for a central with e4. The opening is in effect a reversed Semi-Slav Defense. In response to ...c5 by Black, White typically plays c3. The Colle System was most often played in the late 1920s and 1930s. Colle himself played it from 1925 until his death in 1932. He won many games with the opening, including a number of . Colle–O'Hanlon, Nice 1930, featuring one of the best-known examples of a Greek gift sacrifice, is especially famous.
The opening gained popularity, especially in the United States, through the efforts of Belgian-American International Master George Koltanowski, who remained faithful to it throughout his long career, and wrote several books on it. Koltanowski said he played the opening as a tribute to his friend Colle. The opening is sometimes referred to as the Colle–Koltanowski.
The Colle System fell out of favor in high-level play as good defenses were found for Black. Chess theory today regards it as safe but somewhat passive. However, because of its solid pawn structure, logical piece placement, and coherent strategic aims, the opening is often taught to novice players as a safe and dependable way to reach a middlegame. Thus, the Colle System is frequently seen in amateur and scholastic tournaments, but is not common in professional play; however, it has been used in recent times by grandmasters Pia Cramling, Susan Polgar, Artur Yusupov, who prefers to play with b3 and a fianchetto, a setup known as the Colle–Zukertort, and, most notably, Magnus Carlsen.
