Mars may have had volcanic activity as recently as 50,000 years ago.

Venus and Mars lack plate tectonics, which is a huge driver of volcanoes on Earth. Mars is also a lot smaller and has lost more of its internal heat because of this. Venus has more volcanoes than any other planet, but its thick atmosphere and very high surface pressures makes it harder to study for current activity.
