The Lehigh Valley Interscholastic Athletic Conference (known informally as the Lehigh Valley Conference, or LVC) was an athletic conference consisting of 12 of the larger high schools from Lehigh and Northampton counties in the Lehigh Valley region of Pennsylvania. It was part of District XI of the Pennsylvania Interscholastic Athletic Association (PIAA). In 2014, its teams were mostly assimilated into the even larger 18-team league known as the Eastern Pennsylvania Conference.
