The Nokia Lumia 820 is a smartphone designed, developed and marketed by Nokia. It is the successor to the Lumia 800 and is one of the first Nokia phones to implement Windows Phone 8 alongside the Nokia Lumia 920. Although sharing a similar appearance with the Lumia 800, the Lumia 820 is a major overhaul over its predecessor, sporting a 4.3 inches (110 mm) diagonal OLED display with scratch resistant glass, though lacking Gorilla Glass protection, 1.5 GHz dual-core processor, and an 8.7-megapixel camera. The phone will come with LTE connectivity and a wireless-charging option. The 820 is the first Nokia Windows Phone OS based smartphone to embed a microSD card slot.

On October 9, 2012, the largely similar Nokia Lumia 810 was presented. The main differences are more talk time (10.2 hours) due to the larger 1800 mAh battery, an improved 1.3-megapixel front-facing camera, lighter weight, wider and longer dimensions. The Lumia 810 is exclusively made available to T-Mobile customers in the United States, and as such does not support LTE but only HSPA+, as LTE was not supported in T-Mobile's US network at the time of release.

On October 29, 2012, another variant of the Lumia 820, the Nokia Lumia 822 was announced, having a better front camera, larger battery and double the storage. It is exclusively available for Verizon customers.

The phone features a range of back 'Shells' which will allow users to customise the look of their phone as well as adding functionality such as Wireless charging, if a shell with that capability is added. This feature gives the additional benefit of allowing a scuffed or broken shell to be replaced with a new one to freshen up the device, something which is not possible on some competing smartphones such as the iPhone or unibody Lumia designs such as the 900 and 920. It additionally allows user access to the battery so that a battery which no longer holds a charge can be replaced with a new one, or, if on a long trip away from a charger, the user to swap a spare fully charged battery for an empty one, increasing the time the phone can be used for.
