Thomas de Holand, 1st Earl of Kent (c. 1314–1360), was an English nobleman and military leader during the 14th century. He was the son of Thomas de Holand, 2nd Baron Holand, and became prominent for his service in the Hundred Years' War against France. In 1337, he was created Earl of Kent, a title that elevated his status in the English nobility. Throughout his life, Thomas de Holand was involved in various military campaigns and held several important positions, including serving as a Knight of the Garter. He married Joan of Kent, a significant figure in her own right, and their union strengthened his political alliances. Thomas's legacy continued through his descendants, who played roles in the complex politics of medieval England.
