Sigrid Neef (born 10 October 1944) is a German musicologist and theatre scholar, focused on Russian and Soviet opera.
She has been a dramaturge of the director Ruth Berghaus at the Deutsche Staatsoper Berlin for decades.

Neef has translated numerous Russian and Hungarian operas, for example Glinka's Ruslan and Lyudmila together with Jörg Leipold, and works by Shostakovich, Shchedrin, Kyrill Vokov, Gleb Sedelnikov, Igor Rogaljov, Gennady Banshchikov, and Sándor Balassa.
