The Fukuoka SoftBank Hawks (福岡ソフトバンクホークス, Fukuoka Sofutobanku Hōkusu) are a Japanese professional baseball team based in Fukuoka, Fukuoka Prefecture. They compete in Nippon Professional Baseball (NPB) as a member of the Pacific League. Founded on February 22, 1938, as the Nankai Club, being the first Kansai team to play in Osaka proper, the team went through a few name changes before settling on Nankai Hawks in 1947, eventually changing ownership in 1988 and moving to Fukuoka in 1989. The team subsequently became known as the Fukuoka Daiei Hawks until 2005, when they were purchased by SoftBank Group, becoming the Fukuoka SoftBank Hawks. Since 1993, the Hawks have played at Mizuho PayPay Dome Fukuoka, which has gone under several name changes and seats 40,142 people.

The Hawks are often regarded as one of the most successful franchises in Pacific League and the richest in all of baseball under the ownership of SoftBank Group, with the second most wins in all of Japanese sports, only trailing the Yomiuri Giants. The Hawks have played in the Japan Series 21 different times. The club also won two Japanese Baseball League championships in 1946 and 1948 while the team was based in Osaka. The Hawks' 12 Japan Series championships, including seven championships between 2011 and 2020, and 21 Pacific League pennants, with the most recent of both coming in 2025, are second-most in Pacific League and third-most in all of NPB, only trailing the Saitama Seibu Lions and Yomiuri Giants.

For various reasons, the Hawks experienced a 35 year title drought between 1964 and 1999 including a period of 25 years from 1974 to 1999 without a single Japan Series appearance, despite the relocation to Fukuoka. The drought finally ended in 1999, with gradual additions over the previous five years under new manager and all time home run king Sadaharu Oh. Under Oh (as manager and later executive), Daiei, and later SoftBank, the Hawks embraced internal development and sabremetrics as they eventually formed a baseball dynasty off of a core led by slugger Yuki Yanagita and aces Kodai Senga and Tsuyoshi Wada, capturing Japan Series titles in 2003, 2011, 2014, 2015, 2017, 2018, 2019, and 2020, making the Hawks the first team since the 1965–1973 Yomiuri Giants to win more than three consecutive championships.

Through 2025, the franchise's all-time record is 5,794–5,101–409 (.532). The team's manager is Hiroki Kokubo and the organization's acting CEO is Yoshimitsu Goto [ja].

The franchise that eventually became the Fukuoka SoftBank Hawks was founded on February 22, 1938, by Nankai Electric Railway president Jinkichi Terada as Nankai Club, based in central Osaka. The organization was said to be created as a result of rival railway companies Hanshin Electric Railway and Hankyu convincing Nankai to create a baseball club of their own. While initially met with resistance, the club was admitted to the Japanese Baseball League (JPBL) in the fall of 1938, playing their first games at Sakai Ohama Stadium, but moved into Nakamozu Stadium in 1939. The team's name was changed to Kinki Nippon in mid-1944 as wartime austerity measures forced Nankai to temporarily merge with Kinki Nippon Railway. After the 1945 hiatus in the JBL due to the Greater East Asia War, in 1946 the team's name was changed to Kinki Great Ring and the team won the JBL championship. The name was chosen as a translation of Japan's ancient name, Yamato, in a similar way to the Montreal Canadiens or the New York Yankees.

In mid-1947, when Nankai broke away from Kinki Nippon Railway, they decided to change the team's name, also due to the fact that the name was popular with American soldiers stationed in Osaka, since they also found it funny, and settled upon the moniker they would use until they would sell the team in 1988 – Nankai Hawks (南海ホークス). The team was named after Nankai's logo, which, at that time, was a winged wheel. Other names considered were Condors, which was rejected because the Nankai representative who supervised the team was bald, and Cardinals, which was rejected because the club wanted to retain their colors, so they settled on the Hawks moniker.

After the JPBL was reorganized into Nippon Professional Baseball in 1950, the Hawks were placed into the Pacific League alongside the Mainichi Orions, Hankyu Braves, Tokyu Flyers, Daiei Stars, Nishitetsu Clippers, and Kintetsu Pearls. Under player-manager Kazuto Tsuruoka (known as Kazuto Yamamoto from 1946 to 1958) they became one of the most successful franchises through the first two decades of the Pacific League's existence, taking two Japan Series championships in 1959 and 1964, as well as 10 Pacific League pennants. Kazuto managed the team from 1946 to 1968, becoming the full-time manager after his retirement as a player in 1952.

In 1964, the Hawks team sent pitching prospect Masanori Murakami and two other young players to the San Francisco Giants single-A affiliate in Fresno as a baseball "exchange student". On September 1 of that year, Murakami became the first Japanese player to play in Major League Baseball when he appeared on the mound for the San Francisco Giants at Shea Stadium against the New York Mets. In his debut, Murakami pitched one inning, allowing one hit and facing four batters in a 1–4 loss for the Giants. Disputes over the rights to his contract eventually led to the 1967 United States – Japanese Player Contract Agreement, which effectively barred Japanese players from playing in MLB until Hideo Nomo exploited a loophole in the contract agreement to join the Los Angeles Dodgers in 1995, although others had tried before, including pitcher Kunikazu Ogawa in 1979 for the Milwaukee Brewers and later Murakami himself attempted to return to the Giants in 1983, but both were cut in spring training. Murakami returned to the Hawks in 1966, playing for them through 1974. He contributed to the team's 1973 Japan Series appearance, their last under Nankai's ownership.
