Mildmay Fane, 2nd Earl of Westmorland KB (24 January 1602 – 12 February 1666), styled Lord le Despenser between 1624 and 1628,[1] was an English nobleman, politician and writer.

A friend of Robert Herrick, he supported the Royalist party at the outbreak of the English Civil War (King Charles I had stood as godfather to Fane's eldest son in 1635).

One hundred and thirty-seven poems by Fane appeared in his self-published collection Otia Sacra in 1648—the first time a peer of England published his own verse.

The protagonist of De Pugna Animi is Lord Mens (Mind), who is assisted by figures like Sir Ratio Prudens in resisting a revolt of the five senses.

One of his plays, titled Ladrones, was known in manuscript in the 19th century and reportedly featured Sir Francis Drake, Thomas Cavendish, and Ferdinand Magellan as characters; but the MS. has been lost.
