This Watermelon Mojito is sweet, refreshing, and takes less than five minutes to make. Fresh watermelon cubes get muddled with mint and lime, then topped with white rum and a splash of bubbly club soda. It's the kind of drink you want on a hot day when you're sitting outside and don't want to think too hard.

I made my first one last summer during a backyard cookout, and it was gone before I could even sit down. Now I make them all the time when the weather gets warm. If you love easy summer cocktails, you'll also want to try my Watermelon Slushie and Blue Raspberry Lemonade. And for something non-alcoholic and just as refreshing, my Peach Lemonade is always a hit.

Watermelon Mojito Ingredients
Here's everything you need to make this mint Watermelon Mojito.
See Recipe Card Below This Post For Ingredient Quantities
- Superfine sugar: Dissolves quickly in the lime juice and helps balance the tartness. Regular granulated sugar works too, but it takes a little longer to dissolve.
- Freshly squeezed lime juice: Adds brightness and a citrusy zing that keeps the drink from being too sweet. Bottled lime juice won't taste as fresh.
- Watermelon cubes, seeded and divided: Sweet, juicy, and refreshing. Seedless watermelon makes this easier, but seeded works fine if you remove the seeds first.
- Mint leaves, divided: Cool, herbal, and aromatic. Fresh mint is a must. Dried mint won't give you the same flavor.
- White rum: Light and smooth, it's the perfect base for this cocktail. You can also use vodka if you prefer.
- Club soda or sparkling water: Adds fizz and lightness without extra sweetness. Use plain, not flavored.
How To Make Watermelon Mojito
Here's how to make this refreshing summer drink from start to finish.
- Dissolve the sugar: Place the superfine sugar and freshly squeezed lime juice in a collins or highball glass. Stir with a bar spoon until the sugar is completely dissolved. This creates a sweet-tart base for the drink.

- Muddle the watermelon and mint: Add 3 watermelon cubes and 5 mint leaves to the glass. Use a wooden muddler to gently muddle them 3 to 4 times. You want to release the juices and oils, but don't smash them into a pulp. Just a few gentle presses is enough.

- Add ice and rum: Fill the glass with ice, then pour in 3 ounces of white rum.
- Top with soda: Add a generous splash of club soda or sparkling water. The bubbles make the drink light and refreshing.
- Stir and garnish: Gently stir the mixture with a bar spoon to combine everything. Garnish with the remaining 3 watermelon cubes and 5 mint leaves. Serve immediately.
Substitutions and Variations
You can swap the white rum for vodka if you prefer a cleaner, less sweet flavor. Tequila also works and gives it a fun twist. For a watermelon mojito mocktail, just skip the rum and add extra club soda or sparkling water. If you don't have superfine sugar, use regular sugar or simple syrup. Honey or agave syrup work too, but they'll add a different flavor. For a watermelon mojito recipe with Sprite, swap the club soda for lemon-lime soda. It'll be sweeter and more like a Watermelon Mojito limeade. Fresh basil can replace the mint for a different herbal note.

EQUIPMENT
You'll need a wooden muddler, highball or collins glasses, a bar spoon, a mini measuring beaker set or jigger, and a citrus juicer. If you don't have a muddler, the back of a wooden spoon works in a pinch.
Storage Tips
This drink is best made fresh and served immediately. The ice will melt if it sits too long, and the fizz from the club soda will go flat. If you're making drinks for a group, you can prep the watermelon cubes, mint, and lime juice ahead of time and store them in the fridge. Then just muddle and assemble each drink as guests arrive.
Serving Suggestions
Serve this Watermelon Mojito in a tall glass with a fun paper straw or a reusable metal straw. It's great for backyard cookouts, pool parties, or just sipping on the porch on a hot afternoon. Pair it with grilled chicken, fish tacos, or a fresh summer salad. It also goes well with chips and guacamole, shrimp skewers, or anything off the grill. For a non-alcoholic version, serve the mocktail at baby showers, brunches, or family gatherings.
Expert Tips
Use seedless Watermelon Mojito to save time. If you only have seeded watermelon, make sure you remove all the seeds before cubing. Muddle gently. You want to release the flavors, not pulverize the ingredients. Over-muddling can make the drink bitter. Use fresh mint, not dried. Fresh mint gives you that bright, cool flavor that makes mojitos so good. Don't skip the club soda. The fizz is what makes this drink light and refreshing. Serve immediately. This drink is best enjoyed right after you make it, while the ice is cold and the soda is still bubbly.
