Harry Sacksioni (born 23 October 1950 in Amsterdam) is a composer and guitar virtuoso of Dutch origin. The peak of his fame was during the 1970s to 1990s. Famous works of this period include Meta Sequoia, Vensters and Elixer, along with re-arrangements of existing pieces, such as Anji (Davy Graham), Scarborough Fair (arr. Paul Simon) and I Wish (Stevie Wonder). Sacksioni's work is mainly instrumental, although some tracks during the 1980s provided guitar accompaniments to vocals provided by himself and Raymond van het Groenewoud.

Sacksioni's work is not commercially motivated, and as a result, he is not often featured in the mainstream media. His records appear under an independent, privately owned label Katowee (from: cutaway, a guitar construction property) as a protest against the high prices of CDs.
