The soldiers, who were serving as part of the Coldstream Guards Battle Group, were killed as a result of two improvised explosive device (IED) blasts near Malgir, which lies between Babaji and Gereshk.
Lieutenant Colonel David Wakefield, Spokesman for Task Force Helmand, said:
"It is with deep sadness I must inform you that IEDs claimed the lives of two British soldiers this morning in the Malgir area of central Helmand, an area between Babaji and Gereshk. The soldiers were on a foot patrol when the explosions happened.
"Two of our comrades, taken from us in the course of their duty, whose resolute bravery and sacrifice we will remember."
The soldiers' next of kin have been informed and have asked for a period of grace before further details are released.
