Baliwag Transit Inc. is one of the major bus transportation company in the Philippines with offices and terminals in various parts of Luzon. It mainly services routes to and from Metro Manila and Northern and Central Luzon.

Baliwag Transit Inc. was said to be named after its specific place—present-day Baliuag, Bulacan (It is spelled in Filipino as Baliwag) where it came from.

Baliwag Transit, Inc. is owned by Maria Victoria Santiago Vda. de Tengco or popularly known in Baliwag as "Viuda" or "Nanay", a native of Baliuag, Bulacan. Before the bus company was born in the 1960s, she had a hat business in Baliuag and so, the logo of the bus was a hat. The company grew as years went by and became a member of the Baliwag Group of Companies. The children and grandchildren of Dona Victoria currently manage the company.

Though the company has not been involved in major accidents, cases had been filed against it in the past, where its passenger buses bumped another vehicle while en route to a provincial stop.
