The 11th Anniversary Party was a party that occurred in Club Penguin. It began on October 19th and ended on November 2nd 2016.
- It marked the eleventh anniversary since the launch of Club Penguin in October 2005 (hence the name).
- It was the fifth Anniversary Party to occur during a Halloween Party.
- It was Club Penguin's 150th party (if the Rainbow Puffle Party is included).
- The Coffee Shop music was reused from the 9th Anniversary Party. The decorations themselves were essentially the same except that the cake was different and the decorations had different colours.
- It was the first Anniversary Party to cross over into November.
