3:06 PM PT -- A judge has granted Kelly Clarkson's request for a temporary restraining order until a hearing later this month.
Kelly Clarkson is looking for some serious protection from a woman she claims made multiple unwanted visits to her home ... asking a judge for a restraining order.
According to legal docs, obtained by TMZ, Kelly's requesting a TRO against 56-year-old Huguette Nicole Young ... and the singer also wants her family, her nanny, and her house manager protected from the alleged trespasser.
The docs, filed by her attorney Ed McPherson, say the alleged harassment started at the end of October -- and Michael Lopez, who says he's been running Kelly's security for the past 5 years, claims Young has shown up to her home at least 18 times, often leaving gifts and notes for Kelly.
Lopez claims Young left an assortment of items on Kelly's porch -- including things like dog toys, stickers, plants, and seeds.
The legal docs claim another security guard once told Young she was on camera and is trespassing, and they say she apologized but kept returning to the home after the warning.
