Gorboduc, also titled Ferrex and Porrex, was a transitional English play from 1562. It was performed (as the title page says) before Queen Elizabeth I in January of that year. The authors were Thomas Norton and Thomas Sackville, said to be responsible for the first three Acts, and the final two, respectively.

The play is notable for several reasons: as the first verse drama in English to employ blank verse; for its political subject matter (the realm of Gorboduc is disputed by his sons Ferrex and Porrex), which was still a touchy area in the early years of Elizabeth's reign; for its manner, progressing from the models of the morality play and Senecan tragedy in the direction which would be followed by later playwrights. That is, it can be seen as a forerunner of the whole trend that would later produce King Lear.
