A small safe containing jewellery and cash was also taken from a property in Forest Town, Mansfield, either late on Sunday or early on Monday.
Detective Constable Andre Bak of Nottinghamshire Police said: "A turtle is an unusual item to steal and one that might raise a few eyebrows should the offender try to sell it.
"We are asking anyone who saw the burglary or anything unusual in the area around this time to get in touch with us or Crimestoppers."
