Movember (a portmanteau word from moustache and "November") is an annual, month-long event involving the growing of moustaches during the month of November to raise awareness of prostate cancer and other male cancer and associated charities.

The Movember Foundation runs the Movember charity event, housed at Movember.com. 

The goal of Movember is to "change the face of men's health.

By encouraging men (which the charity refers to as "Mo Bros") to get involved, Movember aims to increase early cancer detection, diagnosis and effective treatments, and ultimately reduce the number of preventable deaths. Besides getting an annual check-up, the Movember Foundation encourages men to be aware of any family history of cancer, and to adopt a healthier lifestyle.

Movember is supported by many Ice Hockey leagues including the National Hockey League & NHLPA, American Hockey League, Canadian Hockey League, and many of the European Hockey Leagues.

The Field Hockey men are also very supportive of Movember, and once again the FIH / International Hockey Federation have their campaign "Hockey Heroes" to support fund-raising efforts.
