In a pitcher, combine lime juice, ginger beer, rum and pineapple juice. Stir well to combine.
Fill glasses with ice and pour in the punch.
If you prefer to make the punch in advance, mix together all of the ingredients except the ginger beer. Refrigerate until ready to serve. Stir in the ginger beer immediately before serving.
