The Weeping Wych Elm , also known as the Horizontal Elm U. glabra Horizontalis is an elm cultivar with branches that extend out horizontally with weeping branchlets. It is usually grafted onto a tall understock of Ulmus glabra to effectively display its weeping habit. It can eventually grow to a height of 20 metres with a similar spread.

The cultivar was discovered in a Perth nursery circa 1816, but first distributed in Germany by Booth of Hamburg, who bought the entire Perth stock. It was originally identified as Pendula by Loddiges (London), in his catalogue of 1836, a name adopted by Loudon two years later in Arb. Frut. Brit 3: 1398, but later sunk as a synonym for Horizontalis. It can be distinguished from the related Camperdown Elm by its more spreading and flattened canopy and larger mature size. Introduced to Australia, the cultivar can be observed in a number of public gardens in Victoria.
