One man is dead and another has been charged with murder after a fight in Western Australia's central wheatbelt.

Police say two men had started fighting in a home in Koorda, a township about 240km northeast of Perth.

A 46-year-old man, identified by police as Gavin John McMaster, died at the scene at about 1.30am (WST) on Saturday.

Police arrested a 64-year-old man and later charged him with murder.

He will appear in the Northam Magistrates Court on Monday.
