Louisiana Highway 42 (LA 42) is a state highway in Louisiana that serves East Baton Rouge, Ascension, Livingston, and Tangipahoa parishes. It spans 46.8 miles (75.3 km) in roughly a Northeast direction.

From the southwest, LA 42 starts at an intersection with LA 30 in Baton Rouge, Louisiana near Louisiana State University. It is a four lane divided highway for 7.6 miles from LA 30 east to an intersection with Highland Road and Siegen Lane in southeastern Baton Rouge. This section is named Burbank Drive.

At the Highland Road intersection, Burbank Drive end curves north and becomes Siegen Lane. LA 42 goes east from this intersection on Highland Road to Airline Highway (US 61). In this segment, it passes the Highland Road Park and Observatory and the Louisiana Country Club. The road gradually curves from east to north, becoming a north-south road immediately south of Interstate 10. The highway intersects I-10 (Exit 166) and becomes a four lane divided highway north to Airline Highway

At Airline Highway LA 42 shares the road with US 61 out of East Baton Rouge Parish and into Ascension Parish in a southeast direction for 3.3 miles. At this point LA 42 turns east and then northeast until it crosses into Livingston Parish and intersects LA 16. For the next 3.1 miles, LA 42 and LA 16 run concurrently, with LA 42 in a northeasterly direction at the end of the concurrency. LA 42 intersects LA 63 in 7.4 miles. About 2.5 miles after LA 63 LA 42 will make an easterly turn, its final major directional shift. It progresses on an easterly path until it ends in Springfield, Louisiana at LA 22.
