State Road 23 is a highway in the north-central part of the U.S. state of Indiana. In practice it runs from the southwest to the northeast, though it is designated as a north–south route. It is an undivided surface road.
From the south, State Road 23 begins at State Road 10 and heads north toward Grovertown. In Grovertown, SR 23 meets U.S. Route 30. SR 23 continues north until Walkerton, where it meets U.S. Route 6. It then turns north-northeast toward South Bend, passing though North Liberty. On the south side of South Bend, SR 23 has an interchange with U.S. Route 20/U.S. Route 31/St. Joseph Valley Parkway. It then passes though South Bend from the southwest to the northeast, continuing though Granger before reaching the Michigan state line.
Between 1917 and 1926, SR 23 began east of Pennville and ran to a point north of Pennville, following today's State Road 1 and State Road 26 routes. Between 1917 and 1926, today's SR 23 route was a county road.
