Gerd Nyquist (15 March 1913 – 22 November 1984) was a Norwegian novelist and children's writer.

She was the granddaughter of government minister Bernhard Brænne (1854-1927) and the mother of novelist and poet Arild Nyquist (1937–2004).

She was awarded the Defence Medal for her participation in the fight against the German occupation of Norway.

She is best known for her two crime novels, Avdøde ønsket ikke blomster from 1960, and Stille som i graven from 1966 featuring detective Martin Bakke.

Both books depict a traditional, bourgeois society from Oslo's west edge.
