Richardis of Sualafeldgau (Richwara;[1] c. 945/950 – 8 July 994) was Margravine of Austria from 976 until 994 as consort of the first Babenberg margrave Leopold I.

[1] Richardis' descent has not been conclusively established: she possibly was a daughter of the Franconian count Ernst IV of Sualafeldgau, or may have been a daughter of the Ezzonid count Erenfried II and his wife Richwara of Zülpichgau.

[1] She was probably also related to Adalbero of Eppenstein, Duke of Carinthia from 1011/12 to 1035.

Richardis married Leopold I (c. 940-994) on a date unknown.

She died in 994, according to several obituaries on the same day her husband was killed in a tournament in Würzburg.
