Biebrich is a borough of the city of Wiesbaden, Hesse, Germany. With over 38,000 inhabitants, it is the most-populated of Wiesbaden's boroughs. It is located south of the city center on the Rhine River, opposite the Mainz borough of Mombach. Biebrich was an independent city until it was incorporated into Wiesbaden in 1926.

Numerous prehistoric and early-historical archeological finds indicate that the Biebrich area has been continuously inhabited since the Neolithic Age. In the Middle Ages, from the beginning of the reign of Charlemagne, the places Biburc (Biebrich) and Moskebach (Mosbach) were part of the Königssondergau Wiesbaden, held by the Frankish king as his personal property.

Biebrich was first mentioned in historical documents in 874. King Louis the German and his entourage boarded vessels at Villa Biburg on a trip from Frankfurt to Aachen.

Beginning of the 18th century, the princes (Fürsten) of Nassau built the Baroque Biebrich Palace (Schloss Biebrich). When this magnificent building was completed in 1744, the Prince of Nassau-Usingen relocated his residence from the far side of the Taunus to Biebrich. Until the completion of the City Palace in Wiesbaden in 1841, Biebrich was the principal residence of the Princes (and, after 1806, the Dukes) of Nassau.

In the 19th century, Biebrich became an important industrial center of the Rhine Main Area with the plants of Dyckerhoff Concrete (now owned by Buzzi Unicem), Kalle and Albert Chemistry (now Celanese), and Henkell (sparkling wine = Sekt). In the economical crisis of the post-World War I Era, the small town, struck hard by unemployment of the majority of his working-class residents, merged with the bigger and much wealthier nearby spa city of Wiesbaden.

In 1951, the 633rd AAA Gun Battalion, 90mm, 7th Army U.S. NATO Occupation Forces were stationed in Biebrich.

Following the composer's wishes, local wind instrument producer Wilhelm Heckel invented the so-called "Heckelphone" (a basso-oboe, used by Richard Strauss, Paul Hindemith, and others).
