National Route 305 (N305) forms a part of the Philippine highway network.

N305 starts at the Magsaysay Bridge as its southern terminus, a pedestrian walkway that used to be a roadway for vehicles, then provided access to the Subic Bay Freeport Zone until 2011 when SM City Olongapo was built.

Magsaysay Drive ends at the Friendship Rotunda, a roundabout intersection that was built in the 1970s.

Going further north, N305 continues the route after the Friendship Rotunda, as Rizal Avenue.

N305 was maintained by the City Government of Olongapo and the Department of Public Works and Highways.
