Guy X of Laval, (born c.1300, died 18 June 1347) was lord of Laval and of Acquigny, baron de Vitré, count of Caserte, and viscount of Rennes. He died 18 June 1347 at the Battle of La Roche-Derrien.

Life
Guy was the son of Guy IX de Laval and Béatrix of Gavre.The accession of Guy in 1333, according to Couanier de Launay would have been celebrated with unusual pomp, and would have been the cause of a claim: a Greek fire at the spire of the Laval Trinity Church.

War in Flanders
Guy accompanied Philip VI of France in his war in Flanders, leading a company of men-at-arms at the Battle of Cassel in 1328.

War of the Succession of Brittany
War erupted in Flanders in 1340, starting with the Siege of Tournai. Guy accompanied John, Duke of Normandy, and John III, Duke of Brittany in a relief force.

In 1341, Guy joined the conflict between Charles of Blois and John of Montfort, for the succession of the Duchy of Brittany. Although he was brother-in-law of John, he joined Charles, husband of Jeanne de Penthièvre his niece. Principal commander during the Battle of Roche-Derrien, on 18 June 1347, he was killed.

Guy's body was brought to Vitré by his widow Béatrix de Bretagne. He is buried in the church Collégiale Sainte-Madeleine de Vitré, where we saw his tomb raised in the choir with a Celtic inscription: "Cy gist noble et powerful seigneur Guy, sire de Laval and Vitré, who died at the Battle of Roche-Derrien on 18 June 1347. Pray to God for him."
