Ulva (; Scottish Gaelic: Ulbha) is a small island in the Inner Hebrides of Scotland, off the west coast of Mull. It is separated from Mull by a narrow strait, and connected to the neighbouring island of Gometra by a bridge. Much of the island is formed from Cenozoic basalt rocks, which are formed into columns in places.

Ulva has been populated since the Mesolithic period, and there are various Neolithic remains on the island. The Norse occupation of the island in the Early Middle Ages has left few tangible artefacts but did bequeath the island its name, which is probably from Ulvoy, meaning "wolf island". Celtic culture was a major influence during both Pictish and Dalriadan times as well as the post-Norse period when the islands became part of modern Scotland. This long period, when Gaelic became the dominant language, was ended by the 19th-century Clearances. At its height, Ulva had a population of over 800, but by May 2019, this had declined to 5; some increase in the number of residents was expected in future, with the re-population plan that was to commence in 2020.

Numerous well-known individuals have connections with the island including David Livingstone, Samuel Johnson and Walter Scott, who drew inspiration from Ulva for his 1815 poem, The Lord of the Isles. Wildlife is abundant: cetaceans are regularly seen in the surrounding waters and over 500 species of plant have been recorded. Today there is a regular ferry service and tourism is the mainstay of the economy. In March 2018 the Scottish Land Fund pledged £4.4 million towards a community buyout of the island, and the North West Mull Community Woodland Company took ownership of the island on 21 June 2018.
