Dennis George Wyldbore Hewitt VC (18 December 1897 – 31 July 1917) was an English recipient of the Victoria Cross.

Hewitt was the son of Elizabeth Mary née Rampini (1871–1959) and Hon.

On 31 July 1917 north-east of Ypres, Belgium, at Pilckem Ridge, when his first objective had been captured, Second Lieutenant Hewitt reorganised his company and moved forward.

Whilst waiting for the barrage to lift, he was hit by a piece of shell which exploded the signal lights in his haversack and set fire to his equipment and clothes.

He extinguished the flames and then, despite his wound and severe pain, he led forward the remnants of the company under a very heavy machine-gun fire and captured and consolidated his objective.
