Oecomys sydandersoni is an arboreal species of rodent in the genus Oecomys. It lives in forest patches in a small area in eastern Bolivia. It is a medium-sized species, weighing about 45 g (1.6 oz), with mostly grayish and brownish fur and short and broad hindfeet with well-developed pads.

First collected in 1964, it was formally described in 2009. The species may be most closely related to O. concolor and O. mamorae, which are distributed further north and south in South America. Among other characters, the three share a particular arrangement of the arteries of the head. Virtually nothing is known of its biology.
