Markkanen nailed five 3-pointers, including a key shot beyond the arc in overtime. Dunn hit two 3's in OT, and converted a pair of free throws near the end to make it a six-point game.
Shaquille Harrison scored 18. Cristiano Felicio added 15 points, and the Bulls won their second straight after dropping five in a row, despite leading scorer Zach LaVine (bruised right thigh, right knee tendinitis) and Otto Porter Jr. (strained right rotator cuff) not playing because of injuries.
Jabari Parker led Washington with 28 points against his former team. Beal scored 27 and hit the tying jumper in the closing seconds of regulation. But the Wizards went 0 for 6 from the field in OT, losing for the third time in four games.
Tied at 113 through four quarters, the Bulls went on an 8-2 run to start overtime, with Robin Lopez hitting two foul shots and Dunn nailing two 3-pointers. It was 121-117 with a minute left when Dunn missed two free throws.
Beal then missed the first and made the final two free throws after getting fouled on a 3, cutting the lead to two. But Markkanen nailed a 3 from the top of the key to make it 124-119 with 32.3 seconds remaining.
Parker then put up an airball on the second attempt after making the first free throw, and Dunn hit two foul shots to make it 126-120 with 19.5 seconds left.
