Gather all ingredients. Rinse and dry the peaches, then chop into small pieces. Finely dice the red onion and jalapeño. Chop cilantro if desired.

In a large mixing bowl, combine diced peaches, red onion, jalapeño, and chopped cilantro. Gently mix with a spatula.

Squeeze fresh lime juice over the mixture and stir gently to incorporate without mashing the peaches.

Sprinkle salt over the salsa mixture and stir well to combine.

Cover the bowl and let the salsa sit for at least 30 minutes to allow flavors to meld.

Give the salsa a final stir before serving with tortilla chips, grilled chicken, or tacos.
