The Mid-Atlantic Prep Hockey League (MAPHL) is a High School Prep Hockey League, currently including members from the Interstate Athletic Conference (IAC), Mid-Atlantic Athletic Conference (MAC), Maryland Interscholastic Athletic Association (MIAA), and Washington Catholic Athletic Conference (WCAC) conferences (Member Conferences). The league exists to promote High School Hockey in the DMV through interconference competition, culminating in an annual MAPHL Championship.

The MAPHL seeks to grow the league through the addition of teams from within the Member Conferences, as well as through the future expansion and inclusion of teams beyond the current Member Conferences.

The MAPHL endeavors to be the premier inter-conference league for high school hockey competition in the DMV.
