Arroyo Pavón is a stream approximately 120 kilometers long that originates near the town of Alcorta and flows through the southern portion of Santa Fe province, Argentina. Its coordinates place it at roughly 33°12′18.4″S 60°20′16.4″W. Along its course, the arroyo receives additional flow from canals and smaller tributaries. The stream is notable for passing through a landscape where waterfalls are geographically uncommon, making the Cascada Pavón — an 8-meter waterfall located about 3 kilometers from the small town of Pavón — a distinctive feature of the waterway.

The arroyo runs between the towns of Villa Constitución and Figuera in the Departamento de Constitución. Access to the area near the waterfall can be made via Route 9, with entry points through either Figuera or Villa Constitución. On the bank opposite the waterfall stand the ruins of an old flour mill. Camping areas and cabin complexes are available in the vicinity, providing basic infrastructure for visitors spending time along this stretch of the stream.

The arroyo supports a variety of fish species including Pati, Trahira, Spotted sorubim, and Golden dorado, indicating a reasonably healthy aquatic environment along at least portions of its length.
