Hermann Robert Josef Senkowsky (31 July 1897 – 5 April 1965) was an Austrian customs officer and SS-Führer.
He reached the rank of Oberleutnant and was an artillery battery commander at the end of World War I.
After his doctorate in 1922 he became a civil servant in the finance administration and in 1928 published his Zollwachvorschrift, customs instructions for Austria, which are, in a modified version, still in use today.
He was relieved of his office in 1934 for his membership in the NSDAP, which was an illegal party in Austria at the time.
In November 1934 he was arrested for participating in the July Putsch, but was released due to lack of evidence.
