Some examples of seedless fruits are:
Seedless watermelon
Seedless grapes
Seedless oranges
Seedless bananas (technically, they have small, undeveloped seeds, but they are usually considered seedless)
Seedless cucumbers
Seedless tangerines
Seedless lemons and limes (also called "acidless" or "sweet" lemons/limes)
It's worth noting that some seedless fruits may still contain some small, undeveloped seeds or traces of seeds,
