Abstract: A hammer holder having a support member for attachment to a belt, garment, tool bag or nail pouch of a hammer user. The hammer holder includes a U shaped chamber integrated with the support member and provides support for the hammer head and for the hammer handle in an upright vertical position when the support member is connected to a belt or a user. The chamber is large enough to contain the head of the hammer and includes stop means which prevents the head of the hammer from passing through the chamber or out the top of the chamber. A clip is attached to the support member for receiving the vertically oriented handle of the hammer and a movable gate member pivotally attached to the support member permits the hammer handle to move into the clip and spring back to prevent the handle from moving out of the clip.
