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.

Weber began recording in the early 1960s, and released The Colours of Chloë (ECM 1042), his first record under his own name, in 1973. In addition to his career as a musician, he also worked for many years as a television and theater director. He has designed an electric-acoustic bass with an additional string tuned to C.

Weber’s music, often in a melancholic tone, frequently utilizes ostinatos, yet is highly organized in its colouring and attention to detail. He was an early proponent of the solid-body electric double bass, which he has played regularly since the early 1970s.
