Mercury is the planet closest to the sun and therefore gets more direct heat​. But it is not the hottest planet.

Venus is the hottest planet in the solar system. Although Venus is not closest to the sun, its dense atmosphere traps heat. As a result, temperatures on Venus are higher than the temperature on Mars.

Venus is the hottest planet even though Mercury is the closest planet to the Sun. The reason that Venus is hotter than Mercury is because it has an atmosphere made of carbon dioxide; it also has clouds of acid inside its atmosphere. This is called greenhouse effect.
