  Recent results on searches for physics beyond the Standard Model obtained by
the H1 and ZEUS experiments are reported here. After a brief introduction to
the HERA collider, indirect searches for contact interactions and
extra-dimensions are presented as well as direct searches for new physics
including leptoquarks, lepton-flavour violation, squarks produced by R-parity
violation and excited fermions. New results from isolated lepton events and
single top searches are also presented. Finally the future prospects of HERA-2
are shown.
