Abstract: A trailer hitch step apparatus including a hollow square-shaped hitch sleeve, with a perimeter of a channel of the hitch sleeve substantially conforming to a perimeter of a trailer hitch receiver. A base mounting support is attached to a bottom side of the hitch sleeve. Each of a right step member and a left step member of a pair of step members is attached to a right area and a left area, respectively, of the base mounting support. Each of a right side mounting support and a left side mounting support of a pair of triangular side mounting supports is disposed on a side edge of the right step member and the left step member, respectively. The channel of the hitch sleeve is selectively slidably disposable around the trailer hitch receiver, and a tightening bolt secures the channel of the hitch sleeve around the trailer hitch receiver.
