The Taymouth Hours (Yates Thompson MS 13) is an illuminated Book of Hours produced in England in about 1325–35. It is named after Taymouth Castle where it was kept after being acquired by an Earl of Breadalbane in the seventeenth or eighteenth century. The manuscript's shelf mark originates from its previous owner, Henry Yates Thompson, who owned an extensive collection of illuminated medieval manuscripts which he sold or donated posthumously to the British Library. The Taymouth Hours is now held by the British Library Department of Manuscripts in the Yates Thompson collection.
