A Brønsted acid‐catalyzed cycloisomerization of functionalized alkynes is described, which is assumed to be initiated through the formation of a benzylic cation intermediate. The reaction offers a highly efficient and straightforward route to indenyl ketones with a wide range of substituents under mild conditions.
