Długa Goślina [ˈdwuɡa ɡɔˈɕlina] is a village in the administrative district of Gmina Murowana Goślina, within Poznań County, Greater Poland Voivodeship, in west-central Poland. It lies approximately 8 kilometres (5 mi) north of Murowana Goślina and 28 km (17 mi) north of the regional capital Poznań. In 2006 the village had a population of 390.

The village stretches for a few kilometres along the road from Murowana Goślina to Rogoźno, as is implied by its name (the prefix Długa is Polish for "long"). It has a wooden church, with relics dating from the 17th and 18th centuries (one of the sites on the Wooden Churches Trail around Puszcza Zielonka). The church is the venue for a regular series of summer music festivals. The village also has a primary school and a volunteer fire brigade. Burned by Kalmyks in 1707.
