The 148th Regiment Pennsylvania Volunteer Infantry was an infantry regiment that served in the Union Army during the American Civil War.
 The 148th Pennsylvania Infantry was composed of volunteers raised chiefly in Centre County, Pennsylvania, with seven companies hailing from the county. Company C in particular was recruited in the area surrounding the Agricultural College of Pennsylvania (today known as Pennsylvania State University) and included many of the college's students. The regiment was filled out with a company each from Clarion, Jefferson, and Indiana Counties. Once companies were raised, the regiment was organized at Harrisburg, Pennsylvania, and mustered in for a three-year enlistment on September 8, 1862, under the command of Colonel James Addams Beaver.
 The 148th Pennsylvania Infantry mustered out of service on June 1, 1865, near Alexandria, Virginia.
 Soldiers from the 148th are featured in the third chapter of MacKinlay Kantor's Pulitzer Prize-winning novel "Andersonville" (1955).
