The 2018 NCAA Men's Water Polo Championship occurred from November 24, 2018, to December 2, 2018, in Stanford, California at the Avery Aquatic Center. This was the 50th NCAA Men's Water Polo Championship. Eight teams across from all divisions participated in this championship.
The six-member selection committee selected eight institutions based on a wide number of factors, primarily number of wins, rigor of schedule, level of availability, an indication of an upward trend or winning consistently, and RPI.[2]
Likewise with the criteria mentioned above, seeding was based on level of ranking, geographic proximity to the finals site, and a projected low level of academic commitments missed.[2] The pots outlined feature what level in the championship institutions competed in, ranging from competing away in the first round for Pot 4 to skipping to the semifinals in Pot 1.
