The Homegrown Invitational Cup is a collegiate basketball tournament in the Philippines.[1] It aims to determine which is the best "homegrown" collegiate team. Homegrown players are those who came directly from the juniors team of the said school. As a rule, each team must have at least 3 players from its roster who came from their junior ranks. The league gained TV coverage in 2006 through Studio 23. Fil-Oil and Flying V are the main sponsors of the tournament, hence this tournament is the first edition of what would eventually become the Filoil EcoOil Preseason Cup.[2]
