A retractable pen adapted for being accommodated in a portable electronic device is provided. The retractable pen includes a housing, a shaft fixed in the housing and having a first ratcheting structure, a cap having a second ratcheting structure movably engaged with the first ratcheting structure, a driving member rotatably sheathing the shaft and having a third ratcheting structure, and an elastic member sheathing the shaft and leaning against the shaft and the driving member. The elastic member constantly drives the driving member toward the first ratcheting structure or the second ratcheting structure. In a first state, the third ratcheting structure leans against the first ratcheting structure. In a second state, the third ratcheting structure is movably engaged with the second ratcheting structure and leans against the first ratcheting structure so as to push the cap away from the housing.
