Terrence Howard says his estranged wife hates black people and she would often call him names like, "monkey" and "n**ger". All this according to new court docs.

Howard is in the middle of nasty divorce — with both sides accusing the other of extreme violence and other hateful conduct.

Howard has filed a new declaration in L.A. County Superior Court — claiming Michelle inexplicably turned from a "loving, gentle" person, into a monster who once threatened to have him killed by some violent Russians.

In the docs, Howard notes Michelle is not black — and claims that when she would get upset, she would scream things like, "[I] never wanted to marry a n**ger in the first place” and “[I] definitely didn't want to be the step mother of some n**ger kids."

As first reported, Howard claims Michelle is trying to extort him over private recordings she allegedly stole from his personal computer — and in the new docs, T.H. alleges his wife threatened to have him "clipped" if he went to police.

Howard says his wife once bragged, "I have a lot of Russian friends who would do it as a favor."

Howard also claims Michelle has jealousy issues — and has attacked him with a bottle after accusing Howard of talking with other women. Howard claims he never struck back.

Terrence has asked the court to issue a restraining order against Michelle. A hearing is set for January 17.
