Vidumavi was a princess of the Northmen in the Third Age, the daughter of Vidugavia.

She wedded Valacar, son of the King of Gondor. They had one son, Vinitharya, who later became known as Eldacar of Gondor.

Although she was fair and noble, the people of Gondor disapproved of Valacar's marriage to her because she was not of the Númenórean race. Their marriage was the first to bring outside blood into the Royal Line of Gondor. This eventually led to the war of the Kin-strife.
