Käbi Alma Laretei (14 July 1922 – 31 October 2014) was an Estonian-Swedish concert pianist.

Her piano teacher was Maria-Luisa Strub-Moresco, who had an indirect influence on the artistic choices of Laretei's later husband, Ingmar Bergman.

Laretei had a long and distinguished career as a pianist, and in the 1960s she played to packed halls in the United Kingdom, Sweden, West Germany, and the United States, including Carnegie Hall.

She recorded piano passages that appear diegetically in Bergman's films, such as Autumn Sonata and The Magic Flute.

She took an early interest in the TV medium, hosted many programmes on literature and music on Swedish TV and, starting with En bit jord (1976; "A lump of earth"), published a number of books on life and music, the last being Såsom i en översättning (2004; "As in a translation", the title being a paraphrase on "Through a Glass Darkly" (Såsom i en spegel)).
