Javad Alizadeh (Persian: جواد علیزاده Javād Alīzādeh Persian pronunciation: [dʒævɒːd(-e) æliːˈzɒːde]; professional name: Javad; born 9 January 1953) is an Iranian professional cartoonist best known for his caricatures of politicians, comic actors, footballers, and for his scientific/philosophical column (including cartoons, caricatures and satire) titled 4D Humor, which has won awards from Italy, China and Japan.

[3] Influenced by his university degree, he considers writing and drawing cartoons as a tool that can translate sufferings, hardships and the mysteries of life into humorous language.

According to the official website of the magazine, the purpose of the publication is "to promote peace, laughter, tolerance, moderation and multidimensional and multilateral insight in Iranian society".

[9] Alizadeh created a humorous mascot called Mad Commentator (Persian: مفسر شوت) who rose to fame after correctly "predicting" the result of the opening match between Argentina and Cameroon at the 1990 FIFA World Cup.

[13] In October 2008, his scientific cartoon on twin paradox in special relativity was shown and studied in the reading class and conference held by CERN Courier.com (The International Journal of High-Energy Physics site) in Trieste, Italy.
