Egon Terzetta (Bulgarian: Егон Терцета) (2 July 1899 – 16 August 1964) was an Italian footballer who played for SK Ticha and SC Vladislav from Varna, Bulgaria.
Terzetta was born in Valona, Ottoman Empire, modern-day Albania, into a family of old Venetian descent.
Terzetta finally settled in the Black Sea port city of Varna, Bulgaria.
With Vladislav, Terzetta won the first ever Tsar's Cup in 1925, captaining the team to its first Championship title.
After the communist take over in Bulgaria, the family moved to Italy and settled in Genoa where Egon resumed his career as a shipping agent.
