The galaxy that will collide with the Milky Way in several billion years is the Andromeda Galaxy.

The galaxy that will collide with the Milky Way in several billion years is the Andromeda Galaxy.

To find this answer, you can refer to scientific research, studies, and observations in the field of astronomy. Scientists have been studying the movements and positions of galaxies for many years, and they have predicted that the Andromeda Galaxy will collide with the Milky Way in the future based on their observations.

The collision of the Andromeda Galaxy and the Milky Way is an event that will occur over a very long timescale, estimated to happen around 4 billion years from now. It's worth mentioning that when galaxies collide, it doesn't necessarily mean that individual stars will collide with each other, as space is mostly empty. Instead, it refers to the gravitational interaction and merging of the galaxies over time.
