HMT Juniper (T123) was a Tree-class minesweeping trawler of the Royal Navy.

The previous day the German naval squadron under Vizeadmiral Wilhelm Marschall received Luftwaffe reports of two groups of ships.

Marschall decided on his own initiative to attack the southernmost group, which was escorted by Juniper.

On the morning of 8 June, Marschall (with the battleships Scharnhorst and Gneisenau, heavy cruiser Admiral Hipper, and four destroyers) intercepted the British ships, sinking Juniper, the tanker Oil Pioneer, and the empty troopship Orama; they spared the hospital ship Atlantis.

Later that same day, Scharnhorst and Gneisenau encountered and sank the aircraft carrier Glorious and the destroyers Acasta and Ardent.
