The 2015 Toyota Owners 400 was a NASCAR Sprint Cup Series race held at Richmond International Raceway in Richmond, Virginia. It was scheduled to be held on April 25, 2015, but was run on April 26, 2015 due to rain. Contested over 400 laps on the 0.75 mile (1.2 km) D-shaped short track, it was the ninth race of the 2015 NASCAR Sprint Cup season. Kurt Busch won the race, his first of the season, while teammate Kevin Harvick finished runner-up. Jimmie Johnson, Jamie McMurray and Joey Logano rounded out the top five.

Joey Logano won the pole for the race. He led 94 laps on his way to a fifth-place finish. Kurt Busch led a race high of 291 laps. The race had twelve lead changes among five different drivers, as well as eight caution flag periods for 53 laps.

This was the 26th career victory for Kurt Busch, second at Richmond International Raceway and first at the track for Stewart-Haas Racing. The win moved Busch up to 18th in the points standings. Chevrolet left Richmond with a 29-point lead over Ford in the manufacturer standings.

The Toyota Owners 400 was carried by Fox Sports on the broadcast Fox network for the American television audience. The radio broadcast for the race was carried by the Motor Racing Network and Sirius XM NASCAR Radio.

Richmond International Raceway (RIR) is a 3/4-mile (1.2 km), D-shaped, asphalt race track located just outside Richmond, Virginia in Henrico County. It hosts the NASCAR Sprint Cup Series and Xfinity Series. "America's Premier Short Track" formerly hosted a NASCAR Camping World Truck Series race, a Verizon IndyCar Series race, and two USAC sprint car races.

Kevin Harvick entered Richmond with a 30-point lead over Joey Logano. Martin Truex Jr. entered 33 back. Jimmie Johnson entered 56 back. Brad Keselowski entered 59 back.

Following an incident from last year's Federated Auto Parts 400, Richmond International Raceway has added metal barriers and more security personnel to prevent fans from scaling the catch fence during the race. With 71 laps to go in last September's race, a man identified as James Dennis climbed to the top of the catch fence overhead of turn 4. This forced David Hoots, competition director for the Sprint Cup Series, to put the race under caution. "It's frustrating and unfortunate," Dennis Bickmeier, track president of Richmond, said Friday. "I was very adamant after hearing about it that fans don't do that. A fan doesn't disrupt an event. You respect it."

The entry list for the Toyota Owners 400 was released on Monday, April 20, 2015 at 11:23 a.m. Eastern time. Forty-five cars were entered for the race. Chase Elliott attempted to make his second career Sprint Cup Series start in the No. 25 Hendrick Motorsports Chevrolet. Ron Hornaday Jr. was on the initial entry list, but The Motorsports Group decided to replace him in the No. 30 Chevrolet, which was driven by Jeff Green who attempted to make his first start since the 2011 Lenox Industrial Tools 301 at New Hampshire Motor Speedway. Reed Sorenson drove the No. 34 Front Row Motorsports Ford that had been driven by Chris Buescher.
