  Leptoquark searches are considered for future experiments at HERA, Tevatron,
LHC, TESLA and THERA. Expected exclusion limits from direct leptoquark searches
(leptoquark pair production and single leptoquark production) are compared with
indirect limits expected from the contact interaction analysis. Strongest
limits on the leptoquark masses and couplings are expected from high luminosity
LHC data. If the leptoquark signal suggested by the existing data is detected
at LHC, with mass below 1 TeV, TESLA will be an ideal place to study leptoquark
properties, provided that the leptoquark Yukawa coupling is not too small.
