The downhole pump gas eliminating seating nipple system generally includes a seating nipple including an upper end, a lower end, and a channel extending between the upper and lower ends. The channel includes a beveled edge below the upper end and a locking lip above the lower end. A plurality of upper gas eliminators are positioned below the beveled edge. A plurality of lower gas eliminators are positioned below the locking lip. A plurality of central gas eliminators are positioned between the upper and lower gas eliminators. Each of the gas eliminators is angled upwardly from inlet to outlet so as to prevent accumulation of gasses within or below the seating nipple, which can lead to gas locking and/or gas interference.
