Boubín, Mountain summit in Šumava National Park, Czech Republic.

Kubany is a rounded summit of migmatite and paragneiss in the Šumava range, rising to 1,362 metres. Its top holds a 21-metre wooden observation tower built in 2004 and opened in May 2005, with 109 steps leading to a gallery 7 by 7 metres at the base and 4 by 4 metres at the top.

The name Bubyn appears in a Latin charter of 1398, meaning Búbův hill. In 1833 a timber-floating reservoir, Boubínské jezírko, was built on the Kaplický potok on the south slope, 2 km from the summit at 925 m, and served its purpose until 1957. In 1858 the Schwarzenberg forester Josef John had the Boubínský prales protected; a monument, Johnův kámen, stands on Srní vrch 1 km west of the summit at 1296 m.

The Czech name, recorded in a Latin document in 1398 as Bubyn, means Búb's hill; German speakers called it Kuboberg after the village of Kubohütten, renamed Kubany in the 19th century. Local legend makes the Boubínský kmet, an old man, the guardian of the Boubín forest.

The shortest route to the summit is the 5 km blue-marked trail from Kubova Huť; red trails also lead up from Vimperk and Volary, and a yellow trail from Šumavské Hoštice. The final climb was converted into a wooden walkway with railings in 2006. The wooden lookout tower has been closed since 2025 because of structural damage.

The Boubínský prales reserve, protected since 1858 on the initiative of forester Josef John, covers 666 hectares on the southern slope between 940 and 1120 metres. Its best-preserved mixed mountain forest holds spruces and firs 300 to 400 years old; the 'Fir King', 57 metres tall with a 5.08-metre girth, fell in a storm in 1970 at the age of 440.
