Rudolph Bodo Hans von Kirchbach (born 22 June 1849 in Auerbach (Vogtland) – died 23 July 1928 in Dresden) was a Royal Saxon army officer who was a Generaloberst in the First World War and awarded the Pour le Mérite.
 He came from the Saxon nobility. Kirchbach and was the son of the Oberland Forest Master Carl von Kirchbach (1799–1893), Privy Council of Finance and Saxon royal chamberlain, and his second wife Josephine von Bodenhausen (1825–1898).
 Kirchbach attended private school in Auerbach and the higher secondary school of Bezzenberger and Opelt in Dresden. He joined the army on 1 April 1863, at the age of 14 years, spending 3 years as a cadet in the Royal Saxon Artillery School in Dresden. In May 1866, Kirchbach was assigned to the 19th (2nd Royal Saxon) Foot Artillery and with this regiment took park in the Austro-Prussian War.  He was promoted in July 1866 to the rank of second lieutenant and in August joined the 12th (1st Royal Saxon) Field Artillery.  He served with this regiment in the Franco-Prussian War and won the Iron Cross (1870).
 In 1872, he was promoted to first lieutenant and captain in 1877.  Between 1878 and 1881 he served as a regimental and brigade adjutant and as adjutant to the King Albert of Saxony.  In 1881, he was appointed battery commander in the 19th (2nd Royal Saxon) Foot Artillery Regiment.  He served from 1884 to 1889 as an instructor at the Artillery and Engineering School in Berlin, gaining promotion to major in 1887.  In 1889 he returned to the 12th (1st Royal Saxon) Field Artillery Regiment as commander of the 1st Abteilung (equivalent to Battalion).  There, in 1891, he was promoted to the rank of lieutenant colonel.  Kirchbach was transferred to the Saxon War Department in 1893, and became a colonel in 1895, when he was placed in command of the 32nd (3rd Royal Saxon) Field Artillery Regiment.  In 1899, now a Generalmajor, he was commander of the 40th (4th Royal Saxon) Field Artillery Brigade, and in 1901, commander of the 23rd (1st Royal Saxon) Field Artillery Brigade.  In 1904 Kirchbach was promoted to Generalleutnant and appointed commander of the 32nd (3rd Royal Saxon) Division.
 In 1907 he was appointed General der Artillerie and commanding general of the XIX (2nd Royal Saxon) Corps. Thus, he held one of the three highest positions in the Saxon army during peacetime. Kirchbach received this post even though he had not previously held a general staff position.  King Frederick Augustus III of Saxony appointed him in 1912 "à la suite" of the 32nd (3rd Royal Saxon) Field Artillery Regiment.  After nearly six years as corps commander, Kirchbach retired at the end of November 1913.
 Within months of retirement, the First World War broke out.  Kirchbach was reactivated and was assigned as the commanding general of the XII (Royal Saxon) Reserve Corps, part of the predominantly Saxon 3rd Army on the right wing of the forces that invaded France as part of the Schlieffen Plan offensive in August 1914.  He served with this corps on the Western Front over the next three years.  He fought in 1914 in the First Battle of the Marne, in 1915 in the First Battle of Champagne, in 1916 in the Battle of the Somme and at the Battle of Passchendaele at Ypres in 1917.  For his service as a corps commander, he was decorated with the Pour le Mérite on 11 August 1916.
 In December 1917, Kirchbach moved to Eastern Front, where he became commander of Armee-Abteilung D, replacing his cousin General der Infanterie Günther Graf von Kirchbach. In January 1918 he was promoted to the rank of Generaloberst.  Armee-Abteilung D was dissolved in October 1918, at which point he retired again.
 With the dissolution of Armee-Abteilung D in early October 1918, he retired after a total of 52 years of service.  He lived in Dresden until his death on 23 July 1928.  He is buried at the Nordfriedhof Cemetery.
 In Dresden on 29 September 1873, Kirchbach married Margaretha von Pawel-Rammingen (born 17 October 1852 in Braunschweig, died 13 September 1931 in Dresden), the daughter of the Duke of Brunswick's Chamberlain and Rittmeister, Albert von Pawel-Rammingen and his wife Elisabeth Martini.  They had a son, Hans-Karl von Kirchbach (1876–1946), who died in late 1946 in Dresden in the Russian Central Prison, and a daughter, Elizabeth von Kirchbach (1874–1946).
