Robert Hale (August 22, 1933 – August 23, 2023) was an American operatic bass-baritone. He was first a leading baritone at the New York City Opera for a decade, where he performed, alongside Beverly Sills, mostly in Mozart operas and in the revival of belcanto opera such as Donizetti's Lucia di Lammermoor.

Hale then shifted to heavier roles, performing the title role of Wagner's Der fliegende Holländer first in 1978 at the Opernhaus Wuppertal, Germany. After his success there, he became in demand to perform the role at leading opera houses in Europe and the United States. He went further and tackled the role of Wotan in Wagner's Ring cycle, which he first performed in Wiesbaden in 1984, then at the Deutsche Oper Berlin in 1986. It became his signature role, performed and recorded worldwide, and he regarded the Berlin company as his artistic home for almost two decades.
