This 737 series was publicly announced on August 30, 2011. The first 737 MAX airplane, named The Spirit of Renton, performed its first flight on January 29, 2016. The 737 MAX series gained FAA certification on March 8, 2017. The first delivery was a MAX 8 on May 6, 2017, to
The 737 MAX series has been offered in four variants, typically offering 138 to 230 seats and a 3,215 to 3,825 nmi (5,954 to 7,084 km) range. The 737 MAX 7, MAX 8 (including the denser, 200–seat MAX 200), and MAX 9 are intended to replace the 737-700, -800, and -900, respectively. Additional length is offered with the further stretched 737 MAX 10. As of June 2019, the Boeing 737 MAX has received 4,934 firm orders and delivered 387 aircraft.

On August 30, 2011, Boeing's board of directors approved the launch of the re-engined 737, expecting a fuel burn 4% lower than the A320neo. Studies for additional drag reduction were performed during 2011, including revised tail cone, natural laminar flow nacelle, and hybrid laminar flow vertical stabilizer. Boeing abandoned the development of a new design. Boeing expected the 737 MAX to meet or exceed the range of the Airbus A320neo. Firm configuration for the 737 MAX was scheduled for 2013.
In March 2010, the estimated cost to re-engine the 737 according to Mike Bair, Boeing Commercial Airplanes' vice president of business strategy & marketing, would be $2–3 billion including the CFM engine development. During Boeing's Q2 2011 earnings call, former CFO James Bell said the development cost for the airframe only would be 10–15% of the cost of a new program estimated at $10–12 billion at the time.
Fuel consumption is reduced by 14% from the 737NG. In November 2014, Boeing Chief Executive Officer Jim McNerney said the 737 will be replaced by a new airplane by 2030, slightly bigger and with new engines but keeping its general configuration, probably a composite airplane.

During the certification process, the FAA delegated many evaluations to Boeing, allowing the manufacturer to review their own product. It was widely reported that Boeing pushed to expedite approval of the 737 MAX to compete with the Airbus A320neo. That aircraft hit the market nine months ahead of Boeing's model.

Boeing aimed to match the 99.7% dispatch reliability of the 737 Next Generation (NG). Southwest Airlines, the launch customer, took delivery of its first 737 MAX on August 29, 2017. Boeing planned to deliver at least 50 to 75 aircraft in 2017, 10–15% of the more than 500 737s to be delivered in the year.
After one year of service, 130 MAXs had been delivered to 28 customers, logging over 41,000 flights in 118,000 hours and flying over 6.5 million passengers.
By March 2019, the 737 MAX had been involved in two fatal accidents within five months,
While the airplanes are out of service, Boeing has been developing and evaluating a software fix to the MCAS that is subject to review by a panel of global aviation regulators. Airline users of the 737 MAX announced daily flight cancellations expected to extend through August 2019. Boeing Chief Executive Dennis Muilenburg said in June 2019 that the planes would get a green light to fly again by the end of the year but declined to provide a timeline. In late June 2019, the FAA discovered a new issue in the flight control system, resulting in expectations of further delays.
