MV Glenartney was a Glen Line cargo twin-screw motor ship that was launched in Scotland in 1915 as Montezuma, renamed Glenartney when she changed owners, and sunk by a U-boat in 1918.

Elder, Dempster & Co ordered the ship from Harland & Wolff, who built her at Irvine, North Ayrshire.

[1] The ship's main engines were a pair of Burmeister & Wain four-stroke single-acting diesels,[2] probably built under licence by Harland and Wolff.

They were rated at 656 NHP,[3] drove a pair of screws, and gave her a speed of about 11+1⁄2 knots (21 km/h).

On the night of 5–6 February she was about 30 nautical miles (56 km) northeast of Cape Bon, Tunisia when the Imperial German Navy U-boat SM UC-54 hit her with a torpedo.
