Could you be killed by a single photon?

If a single photon has high enough energy, could it kill you? Is there a maximum limit to the energy of one photon?

Yes.  From cancer.

Other comments are focusing on "killed instantly by direct energy transfer".  But it's possible for a single gamma ray to turn a cell cancerous.  It's unlikely that your body will ultimately fail in the battle against this cancer, but people do die from cancers caused by radiation, and arguably in most cases it's some one specific cancer cell that starts the chain.
