The following is a list of county roads in Suffolk County, New York. The designations do not follow any fixed pattern. Some designations are deliberately eliminated in order to alleviate confusion with New York State Highways (such as 109 and 114); however, this practice is inconsistent, as other designations including 25, 111, and 112 are duplicated. County Roads 27, 27A, and 27B were deleted in 1988 and replaced with CR 48.
