The Studebaker-Packard Corporation was the entity created by the purchase of the Studebaker Corporation of South Bend, Indiana by the Packard Motor Car Company of Detroit, Michigan, in 1954.

Packard acquired Studebaker in the transaction. While Studebaker was the larger of the two companies, Packard's balance sheet and executive team were stronger than that of the South Bend company.

It was hoped that Packard would benefit from Studebaker's larger dealer network. Studebaker hoped to gain through the additional strength that Packard's cash position could provide. Once both companies stabilized their balance sheets and strengthened their product line, the original plan devised by Packard president James Nance and Nash-Kelvinator Corporation president George W. Mason was that the combined Studebaker-Packard company would join a combined Nash-Kelvinator and Hudson Motor Car Company in an all-new four-marque American Motors Corporation.

Had the complicated set of combinations gone through as planned, the new company would have immediately surpassed the Chrysler Corporation to become the third of America's "Big Three" automobile manufacturers. However, the sudden death of Mason, the selection of the disinterested George W. Romney as his successor, and disputes over parts-sharing arrangements between the companies doomed any chance of completing the proposed merger. This failure to combine the companies effectively sealed the fates of all four.
