Filumena Marturano, sometime performed in English as The Best House in Naples, is a play written in 1946 by Italian playwright, actor and poet Eduardo De Filippo. It is the basis for the 1950 Spanish language Argentine musical film Filomena Marturano, multiple Italian adaptations under its original title, and the 1964 film Marriage Italian Style.

Eduardo De Filippo OMRI, also known simply as Eduardo, was an Italian actor, director, screenwriter and playwright, best known for his Neapolitan works Filumena Marturano and Napoli Milionaria. Considered one of the most important Italian artists of the 20th century, De Filippo was the author of many theatrical dramas staged and directed by himself first and later awarded and played outside Italy. For his artistic merits and contributions to Italian culture, he was named senatore a vita by the President of the Italian Republic Sandro Pertini.
