The NSB El 11 was an electric locomotive which was operated for both passenger and freight trains by NSB. It was the third type of Norwegian electric locomotive with bogies, after the NSB El 7 and NSB El 9. They were manufactured by Norsk Elektrisk & Brown Boveri (NEBB) and Thune mekaniske verksted. The first 35 engines were built between 1951 and 1956 and numbered 112078 to 112112, a second series of 6 engines, the El 11b, was built between 1963 and 1964 and numbered 112145 to 112150. The b-series had minor modifications such as a windshield consisting of two large windows instead of four small ones. A further upgrade of the El 11 became the NSB El 13 locomotive.

Between 1982 and 1983 three El 11s were upgraded for use on the steep Flåmsbana branch line. They have since been replaced by multiple units such as the NSB BM69 and, later, by locomotives such as the NSB El 17. The El 11s was withdrawn from service during the 1990s, with the last use in 1998. There are four preserved engines, two by the Norwegian Railway Club for use on special trains, and two by the Norwegian Railway Museum in Hamar.
