Heterocycles was a peer-reviewed scientific journal covering research on heterocyclic compounds and published by the Japan Institute of Heterocyclic Chemistry. It was established in 1973 and ceased publication in November 2023.{{cite web |first1=Dalmeet |last1=Singh Chawla |date=2024-04-09 |access-date=2024-04-11 |title=A key chemistry journal disappeared from the web.

It has been decided that publication of HETEROCYCLES will be suspended as of December 2023 due to various circumstances. … HETEROCYCLES has completed its role of promoting the recognition of heterocyclic chemistry as a discipline that traverses various fields rather than being limited to one domain. Therefore, we decided to suspend publication at this time.

The notice did not discuss the abrupt deletion of access to existing articles, which were no longer provided to subscribers via the journal's website, despite ongoing library subscriptions.
