In Dutch sports, The Big Three (Dutch: De Grote Drie) (or The (Traditional) Top Three (Dutch: De (Traditionele) Topdrie)) or The Three Top Clubs (Dutch: De drie Topclubs)) are the nicknames for the three most successful rivalling footballclubs in the Netherlands: Ajax from Amsterdam, Feyenoord from Rotterdam and PSV from Eindhoven. Collectively they amounted to 77 of the 134 Dutch Football Championships ever played (as of 2024), and 62 of a possible 70 championships since the introduction of professional football in 1954 (as of 2024). The three clubs generally end up sharing the top three positions and contending for the title. None of them have been relegated from the Eredivisie either, having been participants in all editions since Dutch football was merged into a single top-level competition in the 1956–57 season.
Several other clubs outside the big three have won the Dutch league, with HVV Den Haag having the fourth most national titles behind the Big Three in the Netherlands with 10 in total; however, the last time they won was in 1914.
Ajax, PSV and Feyenoord are the only Dutch clubs which have won European and international competitions. Feyenoord won the European Cup in 1970 and the UEFA Cup in 1974 and 2002, as well as the Intercontinental Cup in 1970. Ajax won the European Cup three consecutive times in 1971, 1972 and 1973, and a fourth time after it was rebranded to the UEFA Champions League in 1995. They also won the UEFA Cup in 1992, the UEFA Cup Winners' Cup in 1987, the Intercontinental Cup of 1972 and 1995, as well as the European Super Cup in 1972, 1973 and 1995. PSV also won the European Cup of 1988 and the UEFA Cup in 1978.
