Åke Sundborg (15 October 1921 – 23 May 2007) was a Swedish geographer and geomorphologist known for his contributions to the hydrology and geomorphological dynamics of rivers.

He was active at Uppsala University where he studied under the supervision of Filip Hjulström eventually succeeding him on the chair of physical geography.

Besides his studies of rivers Sundborg made contributions on the climate of cities, the distribution of loess and the sedimentation of reservoirs and lakes.

[1] By 1956 Åke Sundborg had greatly improved the Hjulström curve diagram adding lines and a higher level of detail.

[1] Together with the other Ph.D. students of Hjulström, Anders Rapp, Valter Axelsson and John O. Norrman, Sundborg was part of what came to be known as the Uppsala School of Physical Geography.
