Johann Nepomuk Franz Xaver Strixner was a German draftsman, lithographer and engraver.

Strixner was the son of the doctor Franz Seraph Strixner and grew up in Wasserburg am Inn. After his first drawing lessons in Wasserburg, Strixner turned to Munich in 1797 to become a student of Hermann Mitterer at the Feiertagsschule, and from 1799 he also learned copper engraving there. In 1804, he engraved the drawing book for his patron Johann Christian von Mannlich, drawn from Raphael's works, for pupils of art and for enthusiasts.

In January 1809, Strixner enrolled in the subject of printmaking at the Munich Academy. In 1808/09, he worked on Albrecht Dürer's Christian-mythological drawings, published by Alois Senefelder as lithographic copies. Together with Ferdinand Piloty, he published a series of 432 lithographs based on drawings by old masters between 1808 and 1815, specializing in the lithographic reproduction of works of old art.

He became particularly well known for his reproduction of the collection of paintings by the brothers Sulpiz and Melchior Boisserée and their friend Johann Baptist Bertram in the form of a larger lithographic work, which appeared in several installments between 1821 and 1840 in 114 sheets. For this purpose, he lived in Stuttgart for several years, where the Boisserée collection was exhibited in the 1820s.
