The '''MTU Turbomeca Rolls-Royce MTR390''' is a turboshaft developed for light helicopter applications by MTU Turbomeca Rolls-Royce (MTR). The engine is designed to power helicopters in the weight range of 5-7 tonnes in both single and twin engine configurations. So far the only application is the Eurocopter Tiger. Test runs of the MTR390 began in 1989 and the first test flight was performed in 1991. The MTR390 received military certification in May 1996 and civil approval in June 1997.
An uprated version, the MTR390-E (Enhanced), has been developed with Spain's ITP.<ref>{{Cite web|url=https://www.mtr390.com/product/technical-information|title=Technical Information}}</ref>
