Example stylus holders for an electronic device are disclosed herein. In an example, the stylus holder is coupled to an outer housing of the electronic device. In addition, the stylus holder includes a sleeve that is to transition between: an extended position, in which the sleeve is projected out of the aperture of the outer housing; and a retracted position, in which the sleeve is retracted into the aperture of the outer housing from the extended position. Further, the stylus holder includes a biasing member disposed within the outer housing and coupled to the sleeve. The biasing member is to bias the sleeve toward the retracted position when the sleeve is in the extended position.
