(1 June 1805[1] – 9 February 1892) was a German immigrant to South Australia, remembered for his part in framing the Real Property Act, which led to the Torrens title system of land registration.

[3] Hübbe, who was away from Adelaide around this time, returned in 1856 to find Torrens's campaign in full swing, and wrote, as "Sincerus", to The Register supporting the Act and making light of the difficulties in its implementation.

In support of Torrens's campaign, Hübbe wrote a booklet The Voice of Reason and History on Conveyancing, drawing on his knowledge of European law, particularly that inherited from Hanseatic League States, but also of France.

The facts pointed out and the ideas thus kindled in the minds of clear-sighted, practical men, who were afterwards seen in the front rank of the contest, were no doubt farther circulated, ... Torrens first laid down his scheme of legal reform, formed his private committee; and prepared the public mind for the contemplated change by a series of telling articles in the public journals.

Perceiving, however, that he was likely to be outflanked by adroit opponents on some intricate points of permanent consequence both in the foundation and practical working of the new system, I ran, unasked by Mr. Torrens and unknown to him, into the breach.

I and other Germans, led on by Beyer, Vosz, and many others, gave him what ever assistance we were able to contribute; and he, finding me well up in the judicial and historical aspects of the matter, encouraged me to write ' The Voice of Reason and History on Conveyancing' (not yet wholly forgotten), and he got Mr. G. F. Angas, in his own generous way, to bear the whole costs of publishing.

[2] In the House of Assembly, in September 1884, E. W. Hawker moved, seconded by J. L. Stirling, that Hübbe be granted £200[6][7] in recognition of his contribution, given gratuitously, to Torrens's Act.
