HMCS Wentworth was a River-class frigate that served with the Royal Canadian Navy during the Second World War.

[5] The name "frigate" was suggested by Vice-Admiral Percy Nelles of the Royal Canadian Navy and was adopted later that year.

[5] 15 Canadian frigates were initially fitted with a single 4-inch gun forward but with the exception of HMCS Valleyfield, they were all eventually upgraded to the double mount.

[6] For underwater targets, the River-class frigate was equipped with a Hedgehog anti-submarine mortar and depth charge rails aft and four side-mounted throwers.

[5] River-class frigates were the first Royal Canadian Navy warships to carry the 147B Sword horizontal fan echo sonar transmitter in addition to the irregular ASDIC.

She began service as a trans-Atlantic convoy escort that month, and was made Senior Officer's Ship of the group in August 1944.

The vessel remained in this function until February 1945, when she returned to Canada to undergo a significant refit at Shelburne, Nova Scotia.
