Gorgo was an ancient Greek poetess who, according to the 2nd-century CE Maximus of Tyre, was a rival of Sappho. Maximus provides further descriptions of Sappho's supposed attacks on these authors, writing that "sometimes she [Sappho] censures them," or "cross-examines" them or even utilizes irony in her attacks on these writers. More specifically, regarding the irony, he compares Socrates's mockery of Ion wherein, before tearing apart the arguments of his opponent, Socrates begins by saying "Good day to you Ion." Likewise, Sappho supposedly begins her invective by proclaiming "I wish the daughter of the house of Polyanax a very good day." It is not entirely clear exactly who this "daughter of the house of Polyanax" is; it may refer to either Gorgo or Andromeda, another rival of Sappho. According to the classicist Stefano Caciagli, it is more likely that the text refers specifically to Gorgo, as Maximus already discusses fragments from Sappho that were insults against Andromeda, and—according to Caciagli—it is unlikely that Maximus would have cited two passages concerning Andromeda and none about Gorgo, for he otherwise never quotes two passages concerning the same rival of Socrates.
