All planets have seasons. Some have longer and shorter seasons then others. On some planets a day is longer then its season.
Of the "inner planets" only Earth and Mars have large enough tilts to give significant seasonal effects.
There is more than one planet that has not tilt. The planets are Mercury, Venus, and Jupiter. The planet's also do not have seasons.
Mainly, there would be no seasons.
Because Earths axis is tilted.
Uranus's axis is tilted horizontally, at an angle of 97.77 degrees from the vertical.
The Earth spins on its tilted axis. This tilt is what causes the seasons. When its axis points towards the sun then it is Summer when it points away is winter.

Earth and Mars. Venus has only a small tilt and Mercury almost no tilt.
Mercury, I believe. It's because its axis isn't tilted.
Uranus and Pluto have a tilt and have extreme seasons. Mars, Saturn, and Neptune have seasons that are similar to ours.
On the contrary, we have seasons precisely because the Earth's axis is tilted.
The seasons are caused by the tilted axis and orbit. The axis is tilted with respect to its orbital plane.

The Earth has seasons because it polar axis is tilted relative to its orbit.
Mars experiences seasons as its neighbor planet Earth. The seasons last longer and spring is its longest season of the year.
Earth, for a start. Actually, you can expect most planets to have at least some tilt in their axes.
