Which planet is most known for its rings?

Saturn is most recognized for its extensive and stunning ring system, making it the planet famously associated with rings in our solar system. These rings are composed primarily of ice particles, along with smaller amounts of rocky debris and dust, which reflect sunlight beautifully and can be observed from Earth using small telescopes. The rings vary in thickness and density and are organized into multiple distinct bands, which adds to their visual appeal and complexity.

In contrast, while Jupiter, Mars, and Mercury do have some type of ring or debris associated with them, none compare to the grandeur and visibility of Saturn's rings. Jupiter has a faint ring system that is difficult to perceive, Mars has two small moons and no significant rings, and Mercury has no rings at all. This remarkable characteristic of Saturn not only makes it visually distinctive but also contributes to much of the scientific interest surrounding the planet, making it the clear answer to the question.
