Cut off both stem ends of the cantaloupe. Place on a cutting board, one flat side down. Using a sharp knife, carefully cut off the peel using a downward slicing motion. Slice in half. Using a spoon, scoop out seeds. Cut into cubes; you should have about 6 cups.
Place cantaloupe in blender; blend until smooth.
Using a fine mesh sieve or cheesecloth, strain cantaloupe purée into a pitcher. You should have about 2 cups.
Add tea, lemon juice, and maple syrup. Stir to combine.
Divide between four glasses filled with ice.
