About NJB

National Junior Basketball is a nonprofit organization that was founded in 1984 by Dennis Murphy, Jr. As a coach at Garden Grove High School in Orange County, California, Murphy had the vision of creating a youth basketball league based on sportsmanship and player development.

NJB has blossomed into a national youth league with participants in 4 states: California, Hawaii, Arizona and Nevada. For those in K-1st grade a Rookie League is provided that stresses the fundamentals of the game and provides tools for personal growth. The core of the organization is centered on the Divisional Play Program that is open for all boys and girls who wish to participate and are in 2nd through 8th grade. For individuals with an advanced skill set, the All-Net and BYT Programs acts as a supplement to the Divisional Program. The program provides additional training to prepare them for high school basketball in the future.

The High School League offers competition and skill training for players in grades 9-12 who did not make their high school team or looking for off-season play.

Our Mission

To inspire our youth; regardless of race, color, creed, or national origin. To practice the ideals of health, citizenship and character. To implant the game elements of safety, sanity, and intelligent supervision; and to keep the welfare of the player first, foremost, and entirely free of adult lust for glory. To emphasize teamwork for all participants.

Everyone is a winner at NJB!
