鲁道夫·克鲁采（法语：Rodolphe Kreutzer，1766年11月15日－1831年1月6日），是一位法国小提琴家，指挥家以及作曲家。他曾写过40出歌剧，他的小提琴演奏在当时也负有盛名。

1798年，克鲁采在维也纳为法国大使让-巴蒂斯特·贝尔纳多特工作时与贝多芬相识。而让克鲁采留名后世的是贝多芬将其创作的《第9小提琴奏鸣曲》题献给他，并以《克鲁采》作为标题。但是克鲁采本人并不欣赏这一奏鸣曲，也从没演奏过它。事实上，贝多芬的此曲本来是要献给乔治·布里治陶尔的，但因为二人发生了矛盾才转而献给克鲁采。

Rodolphe Kreutzer (15 November 1766 – 6 January 1831) was a French violinist, teacher, conductor, and composer of forty French operas, including La mort d'Abel (1810).

He is probably best known as the dedicatee of Beethoven's Violin Sonata No. 9, Op. 47 (1803), though he never played the work, declaring it unplayable and incomprehensible. Kreutzer made the acquaintance of Beethoven in 1798, when at Vienna in the service of the French ambassador, Jean-Baptiste Bernadotte (later King of Sweden and Norway). Beethoven originally dedicated the sonata to George Bridgetower, the violinist at its first performance, but after a quarrel he revised the dedication in favour of Kreutzer.
