  Observations of the spectacular, blazar-like tidal disruption event (TDE)
candidates Swift J1644+57 and J2058+05 show that the conditions required for
accelerating protons to 10^{20} eV appear to be realized in the outer jet, and
possibly in the inner jet as well. Direct and indirect estimates of the rate of
jetted-TDEs, and of the energy they inject, are compatible with the observed
flux of ultra-high energy cosmic rays (UHECRs) and the abundance of presently
contributing sources. Thus TDE-jets can be a major source of UHECRs, even
compabile with a pure proton composition.
