Sin Piedad 2010 (Spanish for "Without pity") was a professional wrestling major show produced by Consejo Mundial de Lucha Libre (CMLL) that took place on December 3, 2010 in CMLL's home arena Arena México in Mexico City, Mexico. The 2010 Sin Piedad was the seventh CMLL event to carry that name, with previous events taking place in 2000, 2001, 2006, 2007 and 2008 and has traditionally been CMLL's major "end of year" event.
