Oskar Boettger (German spelling of surname- Böttger); (March 31, 1844 - September 25, 1910) was a German zoologist who was a native of Frankfurt am Main. He was an uncle to noted malacologist Caesar Rudolf Boettger {1888-1976).

After receiving his doctorate from the University of Würzburg in 1869, he became a paleontologist at Senckenberg Museum in Frankfurt (1870). In 1875 he began work as curator of the museum's department of herpetology.

Boettger is credited for making Senckenberg's herpetological collection one of the best in Europe during his tenure there. He suffered from agoraphobia, and relied on assistants to collect specimens for him. Boettcher was editor of "Katalog der batrachier- Sammlung im Museum der Senckenbergischen naturforschenden Gesellschaft in Frankfurt am Main" and "Katalog der Reptilien- Sammlung im Museum der Senckenbergischen naturforschenden Gesellschaft in Frankfurt am Main", which were catalogs published by the Senckenberg Museum.

In 1911 famed zoologist George Albert Boulenger (1858-1937) dedicated the species Anolis boettgeri to Boettger, which is a Peruvian anole of the family of Polychrotidae. A number of other herpetological species are named after him, including:

Boettger was also a conchologist and entomologist (specialising in Coleoptera)
