Which C.S. Lewis novel features the fictional world of Perelandra?

Perelandra is the C.S. Lewis novel set on the fictional planet also called Perelandra.

Published in 1943, it is the second volume of Lewis’s Space Trilogy, following Out of the Silent Planet and preceding That Hideous Strength. The protagonist, Elwin Ransom, travels to the planet, which is also identified with Venus in the trilogy’s imaginative cosmology.

The story places Ransom in a setting that resembles an unfallen world. He encounters the Green Lady, the planet’s first woman, and faces a sustained spiritual and moral conflict involving temptation, freedom, and obedience. The novel uses planetary adventure to explore theological and philosophical ideas.

Perelandra is sometimes called Voyage to Venus because that was an early working or descriptive title associated with the project. Its published title, however, is Perelandra, making that the unambiguous answer to the question.
