Maryland Route 305 (MD 305) is a state highway in the U.S. state of Maryland. Known as Hope Road, the state highway runs 5.08 miles (8.18 km) from MD 213 in Centreville east to an intersection with Hayden Road and Dean Road in Hope east of its intersection with U.S. Route 301 (US 301) in central Queen Anne's County. MD 305 was constructed from a railroad crossing near the present US 301 intersection east to Hope in the early 1910s. The highway was completed when the section between Centreville and the railroad crossing was built in the early 1920s. Another segment of MD 305, unconnected from the present section, existed near Ingleside from the late 1940s to the mid-1960s.

MD 305 begins at an intersection with MD 213 (Liberty Street) in the northern part of Centreville. The state highway heads east as two-lane Hope Road through a residential area. Upon leaving the town limits, MD 305 passes through farmland. The state highway crosses Three Bridges Branch before intersecting US 301 (Blue Star Memorial Highway) at an acute angle at the hamlet of Carville Station. MD 305 crosses the Centreville Branch of the Northern Line of the Maryland and Delaware Railroad at grade just east of US 301, then continues east through farmland to the hamlet of Hope, where the state highway ends at an intersection with Dean Road and Hayden Road. Hope Road continues east as a county highway toward MD 405.

The first section of MD 305 to be built was from the railroad crossing at Carville Station east to the highway's present eastern terminus at Hope, which was paved as a state aid road by 1915. The highway between Centreville and the railroad crossing was paved in 1923. In 1946, a second, unconnected section of MD 305 was designated on recently-improved Roe Ingleside Road between Carter Road and MD 19 in Ingleside. The Ingleside segment of MD 305 was returned to county maintenance by 1966.

The entire route is in Queen Anne's County.
