Nikon Z-mount (stylised as ${\displaystyle \mathbb {Z} }$) is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the full-frame Nikon Z7 and Nikon Z6. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z50. In July 2020 the entry-level full-frame Z5 was introduced. In October 2020, Nikon announced the Nikon Z6II and Nikon Z7II, which succeed the Z6 and Z7, respectively. The APS-C lineup was expanded in July 2021, with the introduction of the retro styled Nikon Zfc, and in October 2021, Nikon unveiled the Nikon Z9, which effectively succeeds the brand's flagship D6 DSLR.^[1] The APS-C lineup was further expanded with the Nikon Z30, announced at the end of June 2022.^[2] The Nikon Z6III was announced in June 2024.^[3]

Nikon SLR cameras, both film and digital, have used the Nikon F-mount with its 44 mm diameter since 1959. The Z-mount has a 55 mm diameter. The FTZ lens adapter allows many F-mount lenses to be used on Z-mount cameras.^[4] The FTZ allows AF-S, AF-P and AF-I lenses to autofocus on Z-mount cameras. The older screw-drive AF and AF-D lenses will not autofocus with the FTZ adapter, but they do retain metering and Exif data. Z-mount cameras support metering as well as in-body image stabilization (IBIS) with manual focus lenses.

The 55 mm throat diameter of the Nikon Z-mount makes it the largest full-frame lens mount.^[5][6] It is much larger than the F-mount and the E-mount used by Sony mirrorless cameras^[7] but only slightly larger than the 54 mm of both the Canon EF and RF mounts. It is also slightly larger than the 51.6 mm diameter full-frame mirrorless Leica L-Mount.^[8] The Z-mount has also a very short flange distance of 16 mm,^[9] which is shorter than all mentioned lens mounts. This flange distance allows for numerous lenses of nearly all other current and previous mounts to be mounted to Z-mount with an adapter.

The Z-mount 58 mm f/0.95 S Noct lens reintroduced the Noct brand historically used by Nikon for lenses with ultra-fast maximum apertures.^[10][11]

Nikon published a roadmap outlining which lenses are forthcoming when the Z-mount system was initially announced.^[12] The roadmap has been updated multiple times.^[13] As of November 2023 the current version of the roadmap indicates a 35 mm lens left to be released within 2023.^[14][15]
