Penton Hook Lock is the sixth lowest lock of forty four on the non-tidal reaches of the River Thames in England. It faces an island which was until its construction a pronounced meander (a hook) and is on the site of its seasonal cutoff. It is against the left bank marking the church parish medieval border of Laleham and Staines upon Thames in Surrey for many centuries. Until 1965 their county was Middlesex. At 266 ft (81 m) it is the third longest lock on the river.

A bend 1000 yards (900 metres) upstream of the lock, Silvery Sands, hosts Staines Regatta in the sport of rowing annually. On the opposite bank in Thorpe is Penton Hook Marina which occupies lakes once land used for gravel extraction.
