Hosidius Geta (flourished in the late 2nd /early 3rd century) was a Roman playwright. Tertullian refers to him as his contemporary in the De Prescriptione Haereticorum.
Geta was the author of a tragedy in 462 verses titled Medea. It is the earliest known example of a Vergilian cento, that is, a poem constructed entirely out of lines and half-lines from the works of Virgil. The poet used Virgilian hexameters for the spoken parts of the play, and half-hexameters for the choral parts.
