The club was formed in 1946 from the merger of two existing sports clubs whose roots can be traced back to the 1890s, Sampierdarenese and Andrea Doria. Sampdoria currently compete in Serie A.
Both the team name and jersey do reflect this, the first being a combination of the former names, the second incorporating the former teams' colours (blue-white and red-black) in a single design. The team's colours are blue with white, red and black hoops, hence the nickname blucerchiati ("blue-circled"). Sampdoria play at Stadio Luigi Ferraris, capacity 36,536,which it shares with Genoa's other club, Genoa Cricket and Football Club. The derby between the two teams is commonly known as the Derby della Lanterna.
