Anton Costache Bacalbaşa (, commonly known as Toni or Tony Bacalbaşa, pen names Rigolo, Wunderkind, , Jus., Wus., Zig. etc.; February 21, 1865 – October 1, 1899) was a Romanian political journalist, humorist and politician, chiefly remembered for his antimilitaristic series Moş Teacă. Together with his brothers Ioan and Constantin, he entered public life as a republican and socialist militant. For a while, his career was intertwined with that of Marxist doyen Constantin Dobrogeanu-Gherea, who inspired in him the idea of a socialist art addressed to the masses. He was himself a popularizer of Marxist ideas, and one of the first Marxist intellectuals in Romanian political history.
