  We present the cross section for pair production of scalar leptoquarks $LQ$
in $p\bar{p}$ collisions, $p+\bar{p} \to LQ + \bar{LQ} + X$, at the Fermilab
Tevatron in next-to-leading order QCD. Including the higher-order corrections
stabilizes the theoretical prediction and increases the size of the cross
section for renormalization/factorization scales close to the mass of the
leptoquarks. This leads to an increase of the lower bound on the mass of scalar
leptoquarks by up to 15 GeV with respect to earlier analyses.
