The invention discloses a clothes hanger. The clothes hanger includes a bracket, hanging arms connected to the two sides of the bracket and a hook fixed to the upper end of the bracket; each hanging arm includes a connecting base and multiple connecting blocks cooperatively clamped to one another end to end in sequence, c-shaped first embedding grooves used for being cooperatively clamped to the corresponding adjacent connecting blocks are formed in both ends of each connecting block in a central symmetry pattern, one end of each connecting base is connected to the bracket, and the other end of each connecting base is provided with a c-shaped second embedding groove which can be cooperatively clamped to one first embedding groove in the corresponding connecting block at the end. By adopting the structure above, a user can flexibly disassemble and assemble the connecting blocks in a clothes hanger body; in this way, the length of the hanging arms in the clothes hanger body can be manually adjusted, so that the clothes hanger can be used for airing clothes different in size, and thus the application range of the clothes hanger can be expanded.
