Venus does not have mountains in the traditional sense. Its surface is covered in vast plains and volcanic features, and the highest point is Maxwell Montes. It's a shield volcano that rises approximately 8.8 kilometers (5.5 miles) above the average surface level of Venus.

While it's the highest point, it's important to remember that Maxwell Montes isn't considered a mountain in the same way Earth's mountains are. It's a massive volcanic structure that formed over billions of years.
