An externally reinforced tent assembly and a tent. The tent assembly comprises: a first rod member, a second rod member, a first reinforcement member, a second reinforcement member, and a binding device; when the binding device relatively tightens the first reinforcement member and the second reinforcement member, the first reinforcement member or the second reinforcement member tightly abuts against the first rod member or the second rod member to reinforce the first rod member or the second rod member; thereby using the externally-mounted first and second reinforcement members to perform structural reinforcement on the first rod member and the second rod member at a pivot point.
