A dental composition may have good handling properties and low polymerization shrinkage stress, and be capable of producing a cured product having desirable mechanical strength and excellent transparency. A dental composition may include a polymerizable monomer (A), a filler (B), and a polymerization initiator (C), wherein the polymerizable monomer (A) includes a polyfunctional (meth)acrylic monomer (a-1) having an aromatic ring but no hydroxyl group, and a polyfunctional (meth)acrylic monomer (a-2) having an alicyclic skeleton, and the polyfunctional (meth)acrylic monomer (a-1) and the polyfunctional (meth)acrylic monomer (a-2) have a mass ratio (a-1)/(a-2) of 30/70 to 95/5.
