Milden is a small village and civil parish in Suffolk, England. Located around four and half miles from Sudbury it is part of the Babergh district.

The parish contains the Milden Thicks SSSI and the remains of Milden Castlemotte-and-bailey castle on Foxburrow hill. It was built in the 12th century, but today all that remains is the earth mound upon which it was constructed. The mound is a Scheduled Ancient Monument.
