{{#invoke:Infobox|infobox}} 136 Austria is a main-belt asteroid that was found by the prolific asteroid discoverer Johann Palisa on March 18, 1874, from the Austrian Naval Observatory in Pola, Istria.<ref name="Albrecht2001"/> It was his first asteroid discovery and was given the Latin name of his homeland.

Based upon its spectrum, it is classified as an M-type spectrum, although Clark et al. (1994) suggest it may be more like an S-type asteroid.<ref name="Clark1994"/> It shows almost no absorption features in the near infrared, which may indicate an iron or enstatite chondrite surface composition. A weak hydration feature was detected in 2006.<ref name="Hardersen1983"/>

Photometric observations of this asteroid at the European Southern Observatory in 1981 gave a light curve with a period of 11.5 ± 0.1 hours and a brightness variation of 0.40 in magnitude.<ref name="Schober1983"/> As of 2013, the estimated rotation period is 11.4969<ref name="Behrend"/> hours.
