  We perform a threshold resummation calculation for the associated production
of gluinos and gauginos at the LHC to the next-to-leading logarithmic accuracy.
Analytical results are presented for the process-dependent soft anomalous
dimension and the hard function. The resummed results are matched to a full
next-to-leading order calculation, for which we have generalised the previously
known results to the case of supersymmetric scenarios featuring non-universal
squark masses. Numerically, the next-to-leading logarithmic contributions
increase the total next-to-leading order cross section by 7 to 20% for central
scale choices and gluino masses of 3 to 6 TeV, respectively, and reduce its
scale dependence typically from up to $\pm12$% to below $\pm3$%.
