The Valley National 8-Ball League Association (VNEA) is one of the world's largest amateur pool leagues. As of 2020^[update], there are nearly 100,000 individual members in some 1,400 weekly local leagues playing in over 10,000 pool halls, bars and other venues in around 400 different cities, towns and suburbs in 36 U.S. states, and abroad.

The organization was founded in the United States in 1979 by equipment manufacturer Valley-Dynamo as the Valley 8-Ball League Association. It was later known as the Valley National 8-Ball Association, a name the league still uses sometimes Despite its name, it is no longer just national, having leagues in eleven countries, nor limited to the game of eight-ball, as nine-ball is also sponsored. The annual, week-long VNEA International Pool Championships are held in Las Vegas, Nevada. The organization is headquartered in Bay City, Michigan. As of 2020^[update] the president of the VNEA is Marshall Kohtz.

Unlike most leagues, VNEA is tied to a specific brand of pool table, namely those of the Valley-Dynamo company of Richland Hills, Texas. As with most leagues, the league activity in any given geographic area (such as a city and its suburbs, a quadrant of a very large city, or an entire suburban county) is coordinated by an exclusive franchisee. In VNEA terms, these are "Charter Holders". All VNEA Charter Holders are authorized Valley-Dynamo distributors. All venues participating in the Charter Holder's area VNEA leagues must rent or lease their tables from the Charter Holder. As a consequence, VNEA leagues are mostly found in areas where bars and other establishments tend to rent tables from Valley distributors, whereas in other areas where the majority of venues own their pool tables outright other leagues are more common.

The VNEA has active leagues in several countries other than the United States, all of which send teams and individual competitors to the annual International Championships.

VNEA matches must be played on Valley- or Dynamo-brand 7 by 3.5 ft (2.1 by 1.1 m) "bar box" coin-operated pool tables, considerably smaller than the 9 by 4.5 ft (2.7 by 1.4 m) regulation tables used by professionals and in some other amateur leagues.

Regular VNEA league matches are, like those of the BCA Pool League, played in round-robin format between two teams of either five or (less commonly) three players each, with each player on the home team playing one game (frame) versus each player on the visiting team.

VNEA playing rules were originally derived largely from informal American "bar pool", but have become increasingly consistent with the standard rules promulgated by the World Pool-Billiard Association, and used by some other major leagues, including the BCAPL and American Poolplayers Association. Local VNEA charter holders have a great deal of leeway in how games are handicapped, how players are sorted into skill-based divisions, and even in a few cases as to which rules apply. Charter holders often hold regular individual, non-team tournaments and other special events.

Many tournaments have three skill divisions (Regular, Intermediate, and Masters), and provide for individual, mixed-gender scotch doubles, and team play. The Internationals provide for multiple levels of awards and trophies; a team might lose the main competition but may have a chance to win against other eliminated competitors in a "Hard Luck" division a few days later. The Internationals also provide a Classic division for seniors. Singles play is divided into open and women's subdivisions; women are not required to play in the women's division, but men are prohibited from it.
