Ratchet socket for fitting onto a screwed member. The ratchet socket is drivable by a tool to wrench the screwed member. The ratchet socket includes: a cylindrical main body formed with at least one internal circular hole and at least one through hole formed on the circumference of the main body and communicating with the circular hole; and a ratchet mechanism including a ratchet wheel rotatably disposed in the circular hole, a dog member movably accommodated in the through hole and a resilient hoop fitted around the main body to exert a resilient force onto the outer side of the dog member, keeping the dog member resiliently engaged with the ratchet wheel. When the dog member is engaged with the ratchet wheel, the ratchet mechanism provides a ratchet effect and the main body of the socket is one-way drivingly engaged with the ratchet wheel.
