  Measurements of the top-quark mass employing alternative techniques are
presented, performed by the D0 and CDF collaborations at the Tevatron as well
as the ATLAS and CMS experiments at the LHC. The alternative methods presented
include measurements using the lifetime of $B$-hadrons, the transverse momentum
of charged leptons and the endpoints of kinematic distributions in top quark
anti-quark pair ($t\bar{t}$) final states. The extraction of the top-quark pole
mass from the $t\bar{t}$ production cross-section and the normalized
differential $t\bar{t}$ + 1-jet cross-section are discussed as well as the
top-quark mass extraction using fixed-order QCD predictions at detector level.
Finally, a measurement of the top-quark mass using events enhanced in single
top t-channel production is presented.
