Riccardo Drigo (* June 20, 1846 in Padua, Italy; † October 1, 1930 ebenda) was an Italian conductor and ballet composer.

He studied under Jorich and Bresciani in Padua as well as Antonio Buzzolla at the conservatory in Venice. He taught piano and gained success in his hometown as a composer and conductor. He travelled to Russia in 1878 remaining there for over 40 years. In 1879 he was appointed as a conductor at the Italian opera in St. Petersburg. In 1886 he relinquished this position in favor of the more important position as the conductor of the imperial ballet. He worked with most of the leading dancers and choreographers of the day (Marius Petipa, Lev Ivanov) and conducted the premieres of Tchaikovsky's ''The Sleeping Beauty'' and the ''Nutcracker''. In 1899 he composed the music for the famous ''Pas de deux'' from the 2nd Act by Le Corsaire with choreography by Marius Petipa (St. Peterburg, 1899). His own ballet works were also very popular. The ballet ''Les Millions d'Arlequin'' which premiered in 1900 received international acclaim. Drigo occasionally visited Italy during his voluntary exile. He finally returned to Padua in 1920 as the October Revolution did not appeal to him.
