9909 Eschenbach is a main belt asteroid. It orbits the Sun once every 3.60 years. [cite web | url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9909 | title = 9909 Eschenbach (4355 T-1) | work = JPL Small-Body Database Browser | publisher = NASA/JPL | accessdate = 2008-02-05]

Discovered on March 26, 1971 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on photographic plates made by Tom Gehrels with the Samuel Oschin telescope at the Palomar Observatory, it was given the provisional designation "4355 T-1". It was later renamed "Eschenbach" after Wolfram von Eschenbach, a medieval poet. [MPC 34356 "Minor Planet Center"]
