Hemolysins (UK spelling: haemolysins) are certain proteins and lipids that cause lysis of red blood cells by damaging their cell membrane. Although the lytic activity of some microbial hemolysins on red blood cells may be important for nutrient acquisition or for causing certain conditions such as anemia, many hemolysin-producing pathogens do not cause significant lysis of red blood cells during infection. Although hemolysins are able to lyse red blood cells in vitro, the ability of hemolysins to target other cells, including white blood cells, often accounts for the effects of hemolysins during infection.

Most hemolysins are proteins, but others such as rhamnolipids are lipid biosurfactants.
