A woman has been charged with murder after a man was found dead in a suburban home.

The 58-year-old woman is due to face court on Monday, after calling emergency services to a home at Taperoo, in Adelaide's northwest, on Sunday morning.

A 60-year-old man was found dead at the scene.

Police believe the pair were known to each other.

"We're still investigating the circumstances of the relationship," South Australian Police Inspector Christie Matthews told reporters on Sunday before the woman was charged.
