The Microsoft (Nokia) Lumia 435 (RM-1068) is an entry-level Windows Phone that made its debut in January 2015. Included in the first batch of devices to feature Microsoft's branding, the Lumia 435 is similar to the Lumia 530 in specifications.

Features of the phone include a 4-inch 800 x 480 display, Snapdragon 200 CPU with 64.7 x 118.1 mm dimensions and a 2MP rear camera. Both single and dual-SIM variants have been released in various markets.

On January 10, 2015, Brazil's regulatory agency (ANATEL) released documents mentioning the Lumia 435 by name.

The Lumia 435 is the first 4xx series Lumia to date, and is likely the first in a series of phones that will be offered at a lower price point than the 5xx line of Lumias.
