I'm Filipino, so I should know these.. heheh.
There are three Filipino Martial Arts:
Arnis, a Martial Art that is well known and it is from the northern part of the Philippines, Luzon.
Eskrima comes next which is in the middle of the archipelago, Visayas.
Then there is Kali which is the southern Filipino martial art, from Mindanao.

and if you are confused of how to spell Philippines, I will say it:

P h i l i p p i n e s for the country,
F i l i p i n o for the people
