Johann Mohr (12 June 1916 – 2 April 1943) was a captain with the Kriegsmarine during World War II. He was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves of Nazi Germany.

Mohr joined the Reichsmarine in 1934. After serving as first Watch Officer (second-in-command) to Georg-Wilhelm Schulz in {{GS|U-124|1940|2}} on three patrols, in September 1941 he assumed command of the U-boat on six patrols, and sank 27 merchant ships, for a total of 129,292 GRT of Allied shipping.[https://books.google.com/books?id=03o6DwAAQBAJ&q=Johann+Mohr&pg=PT537 Chronology of World War II 1939-1945 by Alessandro Giorgi]{{Dead link|date=October 2023 |bot=InternetArchiveBot |fix-attempted=yes }}

On 25/26 September 1941 Mohr was part of a Wolfpack that attacked convoy HG 73. Mohr sank Empire Stream, Petrel and Siremalm. Rolf Mützelburg sank the steamer Cortes, for which Mohr has been wrongly credited.Rohwer 1999, p. 67.

On 24 November and 3 December 1941 Mohr sank the British light cruiser {{HMS|Dunedin}} and the steamer Sagadahoc.Rohwer 1999, p. 72. On 14 March 1942 British Resource was sunk by Mohr and his crew.Rohwer 1999, p. 85. In March Mohr achieved a run of successes; Ceiba and Acme (17 March), Kassandra Louloudis and E.M. Clark (18 March), Papoose and W.E. Hutton (19 March), Esso Nashville and Atlantic Sun (21 March) and finally Naeco on 23 March completed the run. All but three were United States-owned vessels.Rohwer 1999, pp. 86-87.

He sank four ships from Convoy ON 92 in May 1942; SS Empire Dell, Mount Parnes, Cristales and Llanover.Rohwer 1999, p. 94. On 9 June the Free French corvette Mimosa was engaged and sunk by U-124, the escort screen prevented Mohr from sinking any ships from Convoy ONS 100.Rohwer 1999, p. 102. Mohr persisted, and three nights later, on 12 June, he sank the 4,093grt British steamer Dartford.Rohwer 1999, p. 103. Six days later, Mohr picked up Convoy ONS 102 in the congested Atlantic shipping lanes. He accounted for the American cargo Seattle Spirit, which destroyed 5,627grt.Rohwer 1999, p. 104. Mohr's last success of the year came on 28 December, when U-124 torpedoed and sank the British ship Treworlas (4,692grt).Rohwer 1983, p. 143 [first addition].

On 9 January 1943, Mohr intercepted the United States Navy Convoy TB-1. In a single action Mohr and his crew sank Broad Arrow (7,718grt), Birmingham City (6,194grt), Collingsworth (5,101grt) and the 4,554grt Minotaur; amounting to approximately 24,000 grts.Rohwer 1999, p. 145.

On 2 April 1943, Mohr sailed U-124 to intercept Convoy OS 45. He succeeded in penetrating the escort screen and sinking Gogra (5,190 grt) and Katha (4,357grt) in position {{coord|41|02|N|15|39|W}}.Rohwer 1999, p. 161. The escorts were alerted and began hunting the U-boat. Mohr was killed when U-124 was detected, engaged and sunk with all hands about {{Convert|500|km|nmi|abbr=on}} west of Porto, Portugal, by the British corvette {{HMS|Stonecrop|K142|6}} and the sloop {{HMS|Black Swan|L57|6}}.Clay, Blair.
