Gather the ingredients.
In a large pitcher or bowl, combine the green tea, cucumber puree, mint, and lime juice. Sweeten to taste, if desired.
Cover the pitcher and chill the mixture for several hours.
Strain and discard the mint and cucumber, if desired.
Add ice to each glass. Garnish the rim with sliced cucumbers, if desired. Cucumber also looks nice in the glass not just on the rim. Add mint leaves to the tea, if desired.
