We look for space-time correlations between 2233 gamma-bursts in the Batse Catalogs and 894 upward-going muons produced by neutrino interactions in the rock below or inside MACRO. Considering a search cone of $10^{\circ}$ around GRB directions and a time window of $\pm 200$ s we find 0 events to be compared to 0.035 expected background events due to atmospheric neutrinos. The corresponding upper limit (90$\%$ c.l.) is 0.87 10-9 cm-2 upward-going muons per average burst.

Key words: gamma-ray bursts (GRB)
