Kim Richards spent the night in jail after getting arrested for shoplifting Sunday night ... TMZ has confirmed.

The former 'Real Housewife' was booked into jail around 7:30 PM after store security called LAPD to a Target in the Valley. Law enforcement tells us a security guard nabbed her for allegedly scooping up a "bunch of items" worth more than $600.

Richards got out of the pokey on Monday afternoon. Her bail was $5,000. It's unclear if she was under the influence at the time of this latest arrest. She was also busted in April for allegedly making a drunken scene at the Beverly Hills hotel.

That arrested led to a rehab stint that just ended a few weeks ago.
