Niels-Henning Ørsted Pedersen (sometimes just NHØP, May 27, 1946-April 20, 2005) was a Danish jazz bassist known for his impressive technique and an approach that could be considered an extension of the innovative work of Scott LaFaro.

Pedersen began his professional jazz career in Denmark at the age of 14. At 17 he turned down an offer to join the Count Basie orchestra. During the 1960s he played with several important American jazzmen who were touring in Denmark, including Albert Ayler, Bill Evans, Dexter Gordon, Roland Kirk, Jackie McLean, Bud Powell, and Sonny Rollins. In the 1970s he worked in a duo with Kenny Drew, and began making occasional appearances with the Oscar Peterson Trio. He has also worked with Stephane Grappelli and recorded extensively as a leader.
