The Hertford Union Canal or Duckett's Canal is a short stretch (c. 1.5 km) of canal in the London Borough of Tower Hamlets in East London. It connects the Regent's Canal to the Lee Navigation. It was opened in 1830 but quickly proved to be a commercial failure. It was acquired by the Regents Canal Company in 1857, and became part of the Grand Union Canal in 1927.

Like its 1766 predecessor, the Limehouse Cut, the Hertford Union Canal was intended to provide a short-cut between the River Thames and the River Lee Navigation. It allowed traffic on the Lea heading for the Thames to bypass the tidal, tortuous and often silted Bow Back Rivers of the Lea via a short stretch of the Regent's Canal, and provided a short-cut from the Lea to places west along the Regent's Canal.

The canal was promoted by Sir George Duckett who succeeded in gaining an Act of Parliament that gained its Royal Assent on 17 May 1824, entitled An Act for making and maintaining a navigable Canal from the River Lee Navigation, in the parish of St. Mary Stratford Bow, in the county of Middlesex, to join the Regent's Canal at or near a Place called Old Ford Lock, in the parish of St. Matthew Bethnal Green, in the said county of Middlesex.

The Act authorised Duckett to borrow up to £50,000 to fund construction, and to charge tolls for using the canal, initially one shilling (£0.05) per ton of goods carried.

With Francis Giles appointed as engineer, the canal opened in 1830 and was for some years known as Duckett's Canal or Duckett's Cut. Many local boaters still affectionately refer to it as the "Duckett's". It was not a commercial success, and within a year offers to waive the tolls were being made. For several years around the 1850s it was unnavigable, as a dam was built across it to prevent the Regent's Canal losing water to it. After failed attempts to sell it in 1851, it was eventually acquired by the Regent's Canal Company and became a branch of that canal on 28 October 1857. The new owners removed the dam, and deepened and widened the channel. When the Grand Union Canal Company came into existence on 1 January 1929, it became part of that network. Today, it is maintained by the Canal & River Trust.
