Ma and Pa Kettle at the Fair is a 1952 American comedy film directed by Charles Barton.

It is the fourth installment of Universal-International's Ma and Pa Kettle series, starring Marjorie Main and Percy Kilbride.

Ma and Pa Kettle are trying to raise money to send their daughter Rosie to college, although the couple are unemployed and in debt.

Pa deliberately walks in front of street traffic, hoping to win a monetary injury settlement, but only succeeds in causing a collision.

Ma then decides to participate in contests at the county fair, and Pa buys Emma, an old tired horse, on credit for the Harness Race, promising to pay the owner later with Ma's fair prize winnings.
