Bolsterlang (Alemannic German: Bolschterlang) is a municipality in the district of Oberallgäu in Bavaria in Germany.

In 1169 AD, Count Wolfrad of Veringen transferred a tavern to the Monastery of St. George in Isny, as well as an estate belonging to the priest Wernher.

Bolsterlang belonged to the Austrian monarchy before it became part of Bavaria.

The place was part of the County of Königsegg-Rothenfels, which was exchanged with Austria in 1804 and fell to Bavaria in the Treaty of Pressburg in 1805.
