Fredrik Ullén is a Swedish pianist. He was born in 1968 in Västerås. He studied at the Royal College of Music in Stockholm, where his teachers included Gunnar Hallhagen and Irène Mannheimer. Later studies at the Sibelius Academy in Helsinki included work with Liisa Pohjola.

His solo recordings include Ligeti's complete works for piano, a collection of Chopin transcriptions, and as of May 2006, the first CD in a planned complete cycle of Sorabji's Études transcendantes (100). His first volume of Ligeti's piano works, released in 1996, contained the premiere recording of Ligeti's Book II piano etudes. His complete recording of Sorabji's Études transcendantes (100), if finished, will be the first.

On his website, Ullén mentions a particular interest in contemporary music, as well as music of a complex nature. Examples of highly complex (and extremely technically demanding) music in Ullén's repertoire include the etudes by Ligeti and Sorabji, as well as American composer George Flynn's two hour cycle Trinity. His recordings have received high acclaim from critics.

Future recording projects mentioned on his website include the complete piano works of Alfred Schnittke, Arvo Pärt, and Charles Ives.

In addition to his career as a performer, he is involved in scientific research on music and the brain. Since 2010, he has been Professor of Cognitive Neuroscience at Karolinska Institutet.
