Rudolf Jansen (19 January 1940 – 12 February 2024) was a Dutch pianist who focused on Lied accompaniment and chamber music, touring the world.

He accompanied singers including Elly Ameling, Barbara Bonney, Peter Schreier and Dietrich Fischer-Dieskau.

[4] He toured the world in recitals, and collaborated with singers such as Elly Ameling, Irina Arkhipova, Olaf Bär, Hans Peter Blochwitz, Barbara Bonney, Brigitte Fassbaender, Birgit Finnilä, Monica Groop, Tom Krause, Christiane Oelze, Andreas Schmidt, Edith Wiens,[4] Peter Schreier and Christianne Stotijn [nl],[3] and instrumentalists including Abbie de Quant and Jean-Pierre Rampal.

[3] Jansen taught at the Sweelinck Conservatory, where he established a class for Lied,[3] and at the Musikhochschule Nürnberg; he regularly gave masterclasses for singer/piano duos in the Netherlands and abroad.

[4] When he made a recording of Wolf's Italienisches Liederbuch with soprano Christiane Oelze, Alan Blyth wrote: Rudolf Jansen deserves a notice to himself for his unravelling of all the intricacies of the often independent piano parts and for his outright mastery in giving the keyboard its due without ever stealing the thunder of the singers; his instrument is ideally balanced with the voices in a truthful recording.
