约翰·菲利普·苏萨（英语：John Philip Sousa，1854年11月6日－1932年3月6日）是浪漫主义时代后期的一位美国作曲家及指挥家，主要的作品是美**旅及爱国进行曲，他亦因此而享负盛名。在大约1890年，有英国杂志把精于创作进行曲的苏萨称为「进行曲之王」，苏萨的音乐出版商亦采用这个绰号推广他的音乐，自此「进行曲之王」就变得家传户晓。苏萨最著名的进行曲包括《自由之钟进行曲》、《雷神进行曲》、《华盛顿邮报进行曲》、《忠诚进行曲》（美国海军陆战队进行曲）及《星条旗永不落》（美国国家进行曲）。

John Philip Sousa (/ˈsuːsə/; Portuguese pronunciation: [ˈso(w)zɐ]; November 6, 1854 – March 6, 1932) was an American composer and conductor of the late Romantic era, known primarily for American military and patriotic marches. Because of his mastery of march composition, he is known as "The March King" or the "American March King" due to his British counterpart Kenneth J. Alford also being known by the former nickname. Among his best-known marches are "The Stars and Stripes Forever" (National March of the United States of America), "Semper Fidelis" (Official March of the United States Marine Corps), "The Liberty Bell", "The Thunderer" and "The Washington Post".
