The Battle of Old Church, also known as Matadequin Creek, was fought on May 30, 1864, as part of Union Lt. Gen. Ulysses S. Grant's Overland Campaign against Confederate Gen. Robert E. Lee's Army of Northern Virginia during the American Civil War.

As the opposing armies faced each other across Totopotomoy Creek, a Union cavalry division under Brig. Gen. Alfred T. A. Torbert collided with a cavalry brigade under Brig. Gen. Matthew C. Butler at Matadequin Creek, near the Old Church crossroads. After sharp dismounted fighting, the outnumbered Confederates were driven back to within 1.5 miles (2.4 km) of Old Cold Harbor, which preceded the Union capture of that important crossroads the following day.

Although Butler had successfully gathered the information that Robert E. Lee needed, for the second time in three days—Haw's Shop and Matadequin Creek—the Confederate cavalry had been driven back by their Union counterparts, and in both cases Custer's brigade had provided the crucial force needed to prevail. Casualties were about 90 on the Union side, 188 on the Confederate. The door was open for Sheridan's capture of the important Old Cold Harbor crossroads the next day, leading to the start of the bloody Battle of Cold Harbor.
