Maryland Route 330 (MD 330) is a state highway in the U.S. state of Maryland. Known as Massey Delaware Line Road, the highway runs 3.72 miles (5.99 km) from MD 313 and MD 299 at Massey east to the Delaware state line in eastern Kent County, where the highway continues as Clayton Delaney Road. Massey Delaware Line Road was improved in 1954 but was not brought into the state highway system and designated MD 330 until the late 1980s.

MD 330 begins at a four-way intersection with MD 313 and MD 299 at Massey. MD 313 heads west (northbound) as Galena Massey Road and south as Millington Massey Road, and MD 299 heads north as Massey Road toward Sassafras. MD 330 heads east as a two-lane road that immediately has a grade crossing of the Centreville Branch of the Northern Line of the Maryland and Delaware Railroad just south of the junction of the Centreville and Chestertown branches of the Northern Line. The highway passes by the Massey Aerodrome and through Millington Wildlife Management Area. MD 330 crosses Black Bottom Branch before it reaches its eastern terminus at the Delaware state line, where the road continues east as Clayton Delaney Road in the southwest corner of New Castle County.

The Maryland State Roads Commission reconstructed Massey Delaware Line Road as a gravel road from the railroad crossing to the state line in 1954; however, they decided to leave the highway in the county highway system. The whole length of the highway was brought into the state highway system through a December 1, 1987, road transfer agreement. The highway was designated MD 330 in July 1988.
