An oil-resistant agent and an oil-resistant composition, which are capable of imparting excellent oil-resistance to paper. The oil-resistant composition contains a polysaccharide (1) and an oil-resistant polymer (2). The polysaccharide (1) is preferably starch. The oil-resistant polymer (2) preferably has (a) a repeating unit formed from an acrylic monomer that has a long-chain hydrocarbon group having 7-40 carbon atoms, and (b) a repeating unit formed from an acrylic monomer that has a hydrophilic group. A polyvinyl alcohol or glucose may be present as an additive.
