Preheat oven to 325 degrees Fahrenheit. Mix graham cracker crumbs, sugar, and melted butter until evenly moistened; press into a 9-inch pie pan and bake for 8 minutes. Let crust cool.
Beat cream cheese and sugar until smooth. Add pineapple juice, vanilla, and eggs; blend until creamy. Stir in pineapple chunks.
Pour filling into crust and bake 35-40 minutes until set with a slight jiggle. Cool completely, then refrigerate for at least 4 hours before serving.
Notes
Chill time makes the pie slice clean and easy to serve. You can garnish with toasted coconut for extra tropical flair.
