A fence erecting assembly for anchoring a stretched fence includes a pair of posts that can each be driven into ground. A pair of lower sleeves is each slidable over a respective one of the posts and a pair of tubes is each coupled to a respective one of the lower sleeves. A pair of upper sleeves is each slidable over a respective one of the posts. A pair of support rods is each insertable through a respective one of the tubes such that each of the support rods is oriented to extend diagonally between the posts. A connection point on each of the support rods is attachable to a mounting tab on a respective one of the upper sleeves thereby inhibiting the pair of posts from tipping toward or away from each other. In this way the pair of posts can serve as an anchor point for a stretched fence.
