Hoài Nhơn was the site of an uprising against French colonialism in 1945 (in Bồng Sơn), involving around 8000 people and led by Trịnh Hồng Kỳ.
As much of Bình Định Province, it was the site of severe fighting during the Vietnam War and a major battle in 1966.
In 2019, Hoài Nhơn experienced its most severe drought over the past 15 years along with other districts of Bình Định, with Mỹ Bình Lake reaching dead levels, or having a quantity too low for proper usage. In 2020, Hoài Nhơn has been recognized as a district-level town
