Finzean (/ˈfɪŋən/ FING-ən; Scottish Gaelic: Fìnnean) is a rural community, electoral polling district, community council area and former ecclesiastical parish, which forms the southern part of the Parish of Birse, Aberdeenshire, Scotland. Finzean was the subject of many well-known landscape paintings by the artist Joseph Farquharson, whose family have owned Finzean Estate (which occupies the eastern half of Finzean) since the 17th century. Finzean extends to approximately 8000 hectares in area and had a population of approximately 270 in 2002.

Finzean is pronounced /ˈfɪŋən/. This is due to the original Scots spelling, Finȝean, containing the letter yogh, which was later erroneously confused with the tailed z.

Finzean occupies the upper catchment of the Water of Feugh within the area of the Lower Deeside, the main tributary of the River Dee. The southern boundary of Finzean is the old county boundary between Aberdeenshire and Kincardineshire which follows the Water of Aven (or A'an) from Loch Tennet to the Feughside Inn at Whitestone. The eastern boundary varies slightly between historic parish boundaries and modern-day polling district boundaries, but generally follows the route of the minor road north from Whitestone towards Potarch. The northern boundary of Finzean follows the watershed separating the Feugh catchment from the Burn of Cattie, although it runs slightly to the north of this ridge in the eastern part of the parish, crossing the B976 at Berrysloch. The western boundary of Finzean is the watershed separating the Feugh from Glen Tanar and Glen Esk.

The sparsely populated western half of Finzean, in the higher reaches of the Feugh catchment, is known as the Forest of Birse and does not form part of the Finzean Estate owned by the Farquharson family. The boundary between the Forest of Birse and Finzean Estate is formed by two small tributaries of the Feugh: the Finlets Burn and the Laird's Burn.

The eastern end of Finzean occupies a broad valley which is a patchwork of fields and small woodlands with scattered houses, farms and small settlements. Most of the population of the parish lives in this area, with the main clusters of housing being at Finzean village, Drumhead and Percie. A ridge of low hills (highest point: Tom's Cairn, 310 metres) bounds this valley to the north and separates it from the valley of the Cattie Burn, which lies within the neighbouring community of Ballogie.

To the south and west, Finzean is shielded by higher granite hills which rise to more than 500 metres above sea level. Notable hills which are prominent in views to the south and west include Clachnaben (589 m), which lies outside Finzean, and Peter Hill (617 m), which is the most prominent hill in Finzean (although Gannoch, in the Forest of Birse, is higher at 731 metres). The hills are mostly covered with heather, but along their lower slopes, there are some extensive areas of forestry, most of which is planted with Scots pine and larch. There is also a small area of natural pine forest at Glenferrick and Finlets, which is the most easterly remnant of the ancient Caledonian Forest.

The Twin Trees of Finzean are a natural curiosity that are well known locally and have been included in the Forestry Commission's Heritage Trees of Scotland. The trees are about 100 years old and a branch from one has naturally grafted itself on to its neighbour, joining the two together in a natural arch that featured on old postcards of the area.

The Water of Feugh and the lower part of the Water of Aven are both designated as part of the River Dee Special Area of Conservation due to their importance for populations of Atlantic salmon and Eurasian otter.
