What was the name of Tolkien’s wartime literary society with C.S. Lewis?

Tolkien’s wartime literary society with C.S. Lewis was called The Inklings.

The Inklings were an informal discussion and writing group associated with Oxford University. Members met mainly at The Eagle and Child pub, known to them as the Bird and Baby, and sometimes in rooms at Oxford colleges. Tolkien and C.S. Lewis were among the group’s best-known participants.

The group was active chiefly during the 1930s and 1940s. Members read works in progress aloud, discussed literature, and offered criticism. Tolkien shared parts of The Lord of the Rings with the group, while Lewis developed works that included his science-fiction trilogy and later The Chronicles of Narnia.

The Inklings were not a formal university society with a fixed membership list or official constitution. Their influence came from regular conversation and mutual feedback, making the name a cultural and literary association rather than a publishing organization.
