Don Pedro, Prince of Aragon, is a fictional character from William Shakespeare's play Much Ado About Nothing. In the play, Don Pedro is a nobleman who visits his friend Leonato in Messina, Italy, after a successful military conquest. Don Pedro helps Claudio to woo Hero and helps set up Benedick and Beatrice who together form the two key couples in the play.
 Don Pedro is considered a stable middleman in the story, providing counsel for Claudio and Benedick as well as conversing with Leonato. However, Don Pedro also experiences some dramatic irony: For example, he is deceived by his brother Don John's plot to frame Hero as unchaste.
 Don Pedro has been portrayed by Denzel Washington in the Samuel Goldwyn Company 1993 film Much Ado About Nothing. He was played by Reed Diamond in Joss Whedon's interpretation of the play, which was released in 2012.
 A potential source of the character of Don Pedro is King Piero d'Aragona from Bandello's twenty-second novella. In the novella, the favourite of King Piero woos a young woman named Fenicia. This parallels how Don Pedro's favourite, Claudio, pursues a young woman, Hero. King Piero, in the Bandello story, was based on the historical figure Peter III of Aragon who became King of Sicily in 1282 after the violent uprising of the Sicilian Vespers.
 Much Ado About Nothing was written while Messina, in Sicily, was part of the Spanish Kingdom of Aragon. Hence Don Pedro's presence in Italy despite being a Spanish Prince.
 In many editions, Don Pedro is referred to in his speech prefixes simply as "Prince".
 The name Pedro is the Spanish version of the name Peter. Don is a Spanish honorific that was reserved for Spanish royalty.
 Though he is called Pedro in the speech prefixes, Don Pedro is introduced as Don Peter in both the Folio and first quarto editions.
 Much Ado About Nothing begins with Leonato announcing that Don Pedro, Prince of Aragon, is coming to Messina. Don Pedro arrives with Benedick, Claudio, and his bastard brother, Don John. Leonato invites Don Pedro and company to stay with him and his family. Don Pedro resolves to help Claudio woo Leonato's daughter Hero by disguising himself as Claudio.
 At the party, Don Pedro woos Hero on Claudio's behalf, but Don John convinces Claudio that Don Pedro betrayed him and wooed Hero for himself. After Claudio's misunderstanding is resolved and he and Hero are engaged, Don Pedro offers marriage to Beatrice who quickly turns him down. After Beatrice and Benedick leave the party, Don Pedro hatches a plan to trick Beatrice and Benedick into falling in love with each other. Don Pedro, Leonato, and Claudio discuss how Beatrice is in love with Benedick in front of a hiding Benedick to gull him into loving her.
 Don John tricks Don Pedro and Claudio into thinking Hero has been unfaithful to Claudio, who, with the support of Don Pedro, accuses Hero at their wedding. Even after hearing that Hero has supposedly died, Don Pedro supports Claudio and condemns Hero for being dishonourable. Dogberry reveals Don John's lies to Don Pedro and Claudio. The next day, Don Pedro's original scheme works out and Beatrice and Benedick are married. Benedick tells Don Pedro that he should "Get [himself] a wife".
 Don Pedro's goodness serves to balance out the Don John's wickedness. Many critics contrast Don Pedro's well-intentioned deceptions, both of Beatrice and Benedick and of Hero, with Don John's bitter and malicious deception of Claudio and Don Pedro.
 Don Pedro is the only male character in Much Ado About Nothing to encourage a female character to speak. He tells Beatrice "Your silence most offends me."
 In Janice Hayes's reading of Much Ado About Nothing, Claudio regards Don Pedro as a father figure; Claudio is thus afraid of engaging in "oedipal competition" with him over Hero.
 There has been some debate as to the meaning of Hero's line, about Don Pedro, "Why then, your visor should be thatched". A. G. Newcomer interprets this line to refer to Don Pedro's baldness. Hilda Hulme interprets "thatch" to possibly refer to pubic hair rather than head hair. Others, such as Joost Daalder, follow Hulme's reading. Another possibility is that this line refers to Don Pedro's lack of a beard. It is additionally possible that this line refers to Don Pedro's mask being overly ornate and is a suggestion from Hero that his mask should be more humbly decorated. Contrarily, the mask itself could be lacking hair. In any case, the line is a put-down of Don Pedro.: 1454
