Otho B. Rosenbaum (February 26, 1871 – December 21, 1962) was a career officer in the United States Army. A veteran of the Spanish–American War, Philippine–American War, and World War I, he served from 1894 to 1935, and attained the rank of brigadier general. Rosenbaum's command assignments included the 173rd Infantry Brigade, 155th Infantry Brigade, and 3rd Division, and his awards and decorations included the Silver Star.

A native of Marion, Virginia, Rosenbaum graduated from the United States Military Academy (West Point) in 1894 and began a career in the Infantry. He served in Cuba during the Spanish–American War in 1898 and received the Citation Star for heroism at the Battle of El Caney. When the army created the Silver Star, his Citation Star was converted to the new award. Rosenbaum went on to serve in the Philippines during the Philippine–American War in the early 1900s. As his career progressed, Rosenbaum served with Infantry regiments throughout the United States, frequently in quartermaster, commissary officer, and adjutant posts. During World War I, he commanded first the 315th Infantry Regiment, then several Infantry brigades in succession. He received temporary promotion to brigadier general, and his wartime service included the Battle of Saint-Mihiel, Meuse–Argonne offensive, Lorraine campaign, and Occupation of the Rhineland.

After the First World War, Rosenbaum attended the United States Army Command and General Staff College and United States Army War College, received permanent promotion to brigadier general in 1927, and commanded the 1st Infantry Brigade, 78th Division, 22nd Infantry Brigade, Hawaiian Division, and 3rd Division. He left the army upon reaching the mandatory retirement age of 64 in 1935.

In retirement, Rosenbaum resided in Washington, D.C. and operated two farms in Fairfax County, Virginia. He died in Washington on December 21, 1962 and was buried at Arlington National Cemetery.
