The Mauritius Command is the fourth naval historical novel in the Aubrey-Maturin series by Patrick O'Brian, first published in 1977.

Aubrey is married and the father of twin girls, owner of a cottage with a fine observatory he built. He is more than ready to be back at sea. He and Stephen Maturin join a convoy charged with taking two well-located islands in the Indian Ocean from the French. The mission provides scope for each man to advance in his specialty.

A review written at first publication found the novel to be written in "language deep with detail and the poetry of fact", appreciating the period detail. A later review, written at the reissue, finds the author a graceful writer but sees a difficulty with the novel's structure, building to climaxes that do not occur. Others writing at that time saw the novel more as part of the long series, with humour, erudition and "impeccable period detail".
