Landed gentry is a traditional British social class, consisting of land owners who could live entirely off rental income. Often they work only in an administrative capacity looking after the management of their own lands.

The term "landed gentry" includes four separate groups in England:

The designation originally referred exclusively to commoners in such a position, but usage became more fluid over time; by the late 19th century, it was commonly applied to nobles such as the Duke of Westminster who lived in such a manner. The famous book series Burke's Landed Gentry records the members of this class. Successful burghers frequently tried to use, and often were successful in capitalizing on, their accumulated wealth to establish themselves as landed gentry.

The term landed gentry, although originally used to mean nobility, came to be used of the lesser nobility in England around 1540. Once identical, eventually these terms became complementary, in the sense that their definitions began to fill in parts of what the other lacked. The term gentry by itself as commonly used by historians, so Peter Coss argues, is a construct that historians have applied loosely to rather different societies. Any particular model may not fit a specific society, yet a single definition nevertheless remains desirable. The phrase landed gentry referred in particular to the untitled members of the landowning upper class.
