The Lamplighters League[a] is a turn-based tactics video game developed by Harebrained Schemes and published by Paradox Interactive.

Set in an alternate version of the 1930s, the player must assemble a team of misfits to stop an ancient cult named the Banished Court, which aims to achieve world domination.

Members of the Lamplighters League must try to disrupt the progress of the game's three hostile factions as they wreak havoc around the world.

[10] In October 2023, Paradox Interactive announced that the commercial reception for The Lamplighters League was "too weak", leading to $22.7 million reduction in pre-tax profit.

They also confirmed reports that significant layoffs had taken place at Harebrained Schemes, prior to the completion of the game.
