"The Taill of the Uponlandis Mous and the Burges Mous", also known as "The Twa Mice," is a Middle Scots adaptation of Aesop's Fable The Town Mouse and the Country Mouse by the Scottish poet Robert Henryson. Written around the 1480s, it is the second poem in Henryson's collection called The Morall Fabillis of Esope the Phrygian.

"The Town Mouse and the Country Mouse" is one of Aesop's Fables. It is number 352 in the Perry Index and type 112 in Aarne–Thompson's folk tale index. Like several other elements in Aesop's fables, "town mouse and country mouse" has become an English idiom.
