A garment ironing assembly includes a panel that has a top side, a bottom side and a perimeter edge. The perimeter edge includes a front edge, a back edge, a first lateral edge and a second lateral edge. A pair of first extensions each is hingedly coupled to the bottom side. Each of the first extensions is selectively positionable and releasably retained in an extended position. One of the first extensions is extendable outwardly from the first lateral edge and one of the first extensions is extendable outwardly from the second lateral edge. Each of the first extensions is positioned adjacent to the front edge. Each of the first extensions is angled away from the front end when the first extensions are in the extended position. A support structure is attached to and extends downwardly from the bottom side of the panel to support the panel above a support surface.
