A fence post platform attachment device fits on top of a T-post has a top platform portion that allows objects such as birdhouses, signs, sprinklers, lockboxes, etc. to be secured to the T-post. A cross-shaped body portion is formed by bending a sheet of steel into a hollow cross shape and welding it to the top platform portion. A series of holes are disposed along the corners of the top platform portion to allow a user to attach the desired object. Fasteners such as bolts securely hold the selected objet to the top platform portion thereby securing it to the T-post fence post.
