Eberhard Weber (born 22 January 1940, in Stuttgart, Germany) is a German double bassist and composer. As a bass player, he is known for his highly distinctive tone and phrasing. Weber’s compositions blend chamber jazz, European classical music, minimalism and ambient music, and are regarded as characteristic examples of the ECM Records sound.

From the early 1960s to the early 1970s, Weber’s closest musical association was with pianist Wolfgang Dauner. Their many mutual projects were diverse, from mainstream jazz to jazz-rock fusion to avant-garde sound experiments. During this period, Weber also played and recorded with pianists Hampton Hawes and Mal Waldron, guitarists Baden Powell de Aquino and Joe Pass, The Mike Gibbs Orchestra, violinist Stephane Grappelli, and many others.

Starting with The Colours of Chloë, Weber has released 13 more records under his own name, all on ECM. The ECM association also led to collaborations with other ECM recording artists such as Gary Burton (Ring, 1974; Passengers, 1976), Ralph Towner (Solstice, 1975; Solstice/Sound and Shadows, 1977), Pat Metheny (Watercolors, 1977), and Jan Garbarek (10 recordings between 1978 and 1998).
