IC 4665 is one of only a dozen young open clusters with a ``lithium depletionboundary" (LDB) age. Using an astrometrically and spectroscopically filteredsample of cluster members, we show that both the positions of its low massstars in Gaia absolute colour-magnitude diagrams and the lithium depletion seenamong its K- and early M-stars are discordant with the reported LDB age of (32+4/-5) Myr. Re-analysis of archival spectra suggests that the LDB of IC 4665has not been detected and that the published LDB age should be interpreted as alower limit. Empirical comparisons with similar datasets from other youngclusters with better-established LDB ages indicate that IC 4665 is bracketed inage by the clusters IC 2602 and IC 2391 at (55 +/- 3) Myr.

A revised age greater than 50 Myr for the young cluster IC 4665
