* W.B. Yeats: Another poet who wrote verse plays, notably "The Countess Cathleen" (1892) and "The Shadowy Waters" (1900).
* A.R. Gurney: More contemporary, Gurney is known for his play "Love Letters," which is written in epistolary form, with the characters' letters forming the dialogue.
* Eugene O'Neill: Though not solely a verse playwright, O'Neill experimented with verse in some of his works, like "Mourning Becomes Electra" (1931).
