Microsoft Office 2021 (third release codenamed Office 16) is a version of the Microsoft Office suite of applications for the Microsoft Windows and macOS operating systems. It was released on October 5, 2021, along with Windows 11, and replaced Office 2019. A successor, Microsoft Office 2024 is expected to be rolled out in the second half of 2024.

Office 2021 retains the same major version number of 16 that previous versions of Office had. It introduces new dynamic arrays, XLOOKUP features for Excel, full dark-mode support and performance improvements. Support for retail versions of Office 2021 will end on October 13, 2026; unlike older versions of Office, there is no extended support period.
