Background
International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the 2023 IMSA SportsCar Championship (IMSA SCC) in August 2022. It was the ninth year the event was held as part of the WeatherTech SportsCar Championship, and the fifteenth annual running of the race, counting the period between 2006 and 2013 when it was a round of the Rolex Sports Car Series and the American Le Mans Series respectively. The 2023 Grand Prix of Long Beach was the third of eleven scheduled sports car races of 2023 by IMSA, the shortest of the season in terms of distance, and it was the first round held as part of the WeatherTech Sprint Cup. The race was held at the eleven-turn 1.968 mi (3.167 km) Long Beach street circuit on April 15, 2023.

After the 12 Hours of Sebring four weeks earlier, Pipo Derani, Alexander Sims, and Jack Aitken led the GTP Drivers' Championship with 670 points, ahead of Filipe Albuquerque, Ricky Taylor, and Louis Delétraz with 660 points followed by Sébastien Bourdais, Renger van der Zande, and Scott Dixon with 600 points. With 708 points, GTD Pro was led by Jules Gounon, Daniel Juncadella, and Maro Engel with a twenty-six point advantage over Ben Barnicoat and Jack Hawksworth. In GTD, the Drivers' Championship was led by Brendan Iribe, Ollie Millroy, and Frederik Schandorff with 629 points; the trio held a one point gap over Corey Lewis, Bryan Sellers, and Madison Snow. Cadillac, Mercedes-AMG, and McLaren were leading their respective Manufacturers' Championships, while Whelen Engineering Racing, WeatherTech Racing, and Inception Racing each led their own Teams' Championships.

On April 3, 2023, IMSA released the latest technical bulletin outlining Balance of Performance for the GTP, GTD Pro, and GTD classes. In GTP, all cars received weight reductions compared to Sebring. The Cadillac ran at the lowest weight (1031 kg), with the BMW and Porsche at 1036 kg, and the Acura at 1045 kg. As a result, the Cadillac ran on 513 kilowatts of power, while the BMW ran on 515 kW (up 2 kW from Sebring), the Porsche ran on 515 kW (down 2 kW from Sebring), and the Acura on 520 kW. Maximum stint energy figures were also adjusted. In GTD Pro and GTD, the Acura and BMW received weight adjustments. The Corvette, Lamborghini, and the Mercedes received air restrictor size changes. Other changes included a change in fuel tank capacity for almost all cars, except the BMW and Mercedes, and an adjustment of average power delta.

Entries
A total of 28 cars took part in the event, split across three classes. 8 were entered in GTP, 5 in GTD Pro, and 15 in GTD. Risi Competizione and Iron Lynx were absent in GTD Pro while Turner Motorsport moved its entry to GTD. In GTD, Jeroen Bleekmeolen replaced David Brule in the #92 Kelly-Moss lineup.

After a ten-minute interval, GTP vehicles drove onto the track. Regulations stipulated teams to nominate one qualifying driver, with the fastest laps determining each classes starting order. IMSA arranged the grid to put GTP vehicles ahead of the GTD Pro and GTD cars.

Qualifying was broken into two sessions. The first was cars in the GTD Pro and GTD classes.

Hyett walked away from the incident unhurt. For causing the red flag, both the No. 93 and No. 80 had their best two times from the session deleted. Due to the extensive damage on their cars, Racers Edge Motorsports with WTR and AO Racing Team withdrew from the event.

The final session of qualifying was for the GTP class. Several teams scrubbed tires in the first half of the session for the race.

Post-race
Ricky Taylor expressed his disappointment after crashing out on the penultimate lap: "I’m very sorry for Acura, HPD and the WTRAndretti team. With the [previous] Acura ARX-05, this was always the track where we had the most performance deficit to the field. It just says so much about Acura, HPD, ORECA and Wayne Taylor Racing with Andretti Autosport to turn our weakest track into our strongest track [with the new Acura ARX-06]. Unfortunately, we got behind with a little issue mid race, but we had such a strong car while fighting back. It came down so close in the end, if we had more time maybe I would have been more patient, but we just wanted to win this for Acura. Everyone at Acura, HPD and Wayne Taylor Racing with Andretti Autosport deserved to win this today and it’s just disappointing, but I’m just so proud to drive an Acura and be part of this team." Jaminet admitted he saw Taylor's overtake attempt happening: "I kind of saw it coming. He had fresher tires and I got held up in traffic the lap before. It was two to go and he went for us. I braked very late and I just saw he was going and if he could make it stop I’d be impressed."

Hawksworth described the No. 14 Lexus victory in GTD Pro as a "perfect weekend": "One of the best-executed races we’ve been a part of. It was good to clear Sorensen off the start, and that put our Lexus RC F GT3 up at the front. Had an amazing pit stop and then Ben drove his tail off from there."

De Angelis admitted the No. 27 Aston Martin couldn't keep pace with the GTD class winning No. 1 BMW: "We just didn’t have the pace of the BMW. We are looking long term and want to win the championship. I’m still disappointed we didn’t win the race today, but we still have to be happy for good points."

As a result of winning the race, Tandy and Jaminet advanced from fifth to first in the GTP Drivers' Championship. In GTD Pro, Barnicoat and Hawksworth moved to first after being second coming into Long Beach. In the GTD Drivers' Championship, De Angelis and Sørensen advanced from fifth to second while Iribe and Millroy dropped from first to fourth. Additionally, Foley and Gallagher jumped from eighth to fifth. Cadillac continued to top their respective Manufacturers' Championship while Lexus took the lead of the GTD Pro Manufacturers' Championship while BMW took the lead of the GTD Manufacturers' Championship. Porsche Penske Motorsport, Vasser Sullivan Racing, and Paul Miller Racing took the lead in the trio of Teams' Championships with eight races left in the season.
