Professional Football Club Ludogorets 1945 (Bulgarian: Професионален Футболен Клуб „Лудогорец 1945“, romanized: Profesionalen Futbolen Klub „Ludogorets 1945“), commonly known as Ludogorets Razgrad or simply Ludogorets, is a Bulgarian professional association football club founded in 1945 based in Razgrad which currently competes in the First Professional Football League, the top-tier of the Bulgarian football league system.
In their inaugural 2011–12 season in A Group after promotion, Ludogorets won the treble by capturing the league championship, the Bulgarian Cup and the Bulgarian Supercup. Subsequently, the club made a significant continental impact in the 2013–14 UEFA Europa League when they reached the Round of 16 in only their second European run. To date they have reached the knockout stages of the Europa League four times, more than any other club in Bulgaria. Ludogorets are also only the second Bulgarian team after Levski Sofia to enter the group stage of the UEFA Champions League, a feat which they achieved in the following 2014–15 season. During that same campaign, they became the first Bulgarian team to score points in the modern Champions League group stage following a 1–0 win over Basel in Sofia.
Since their introduction to the Bulgarian top-flight in 2011, Ludogorets have established themselves as a dominant force in Bulgarian football, claiming every possible league title since then. They have also won the Bulgarian Cup twice, as well as the Bulgarian Supercup on four occasions.
Ludogorets' traditional home colours are green and white. The club's home ground is the Huvepharma Arena in Razgrad, a stadium with a capacity of 10,500 spectators. Their current manager is Ante Šimundža.
