KTM（全称KTM Sportmotorcycle AG）是一家奥地利电单车、单车和助力车（moped）制造商，于1934年由工程师汉斯·特鲁肯波尔兹（Hans Trunkenpolz）于奥地利城镇马迪霍芬（Mattighofen）创立。公司最初专营金属加工，店名为Kraftfahrzeuge Trunkenpolz Mattighofen（马迪霍芬特鲁肯波尔兹汽车，简称KTM）。1954年起，KTM开始制作电单车。

KTM以制造越野电单车驰名，但近年也开始涉足一般街道电单车和跑车的制造。

KTM-Sportmotorcycle AG is an Austrian motorcycle manufacturer, which was formed in 1992 but traces its foundation as early as in 1934. In 1992 the company was spun off from its parent company KTM when it ran into financial troubles. KTM was split into four companies, all of which shared the same KTM branding, and in present have many more subsidiaries with the same branding. However, KTM-Sportmotorcycle is most commonly associated with the KTM brand, because it still continues the flagship business of its parent company.
