HM V is a class of two-bogie four-axle (Bo′Bo′ wheel arrangement) tram operated by Helsinki City Transport (Finnish: Helsingin kaupungin liikennelaitos, abbreviated HKL; Swedish: Helsingfors stads trafikverk, abbreviated HST) on the Helsinki tram network.

HKL ordered the HM V type trams from Karia, a subsidiary company of Suomen Autoteollisuus, in 1957.

Karia built the bodies and assembled the trams, while Sisu (another subsidiary company of Suomen Autoteollisuus) supplied the bogies and Strömberg the electronics.

The HM V trams were built to be compatible with the HP II type trailers that had been constructed in 1958–59, also by Karia.

[2] During the latter half of the 1990s HKL ordered 40 low-floor Variotrams, which were projected to replace the HM V and RM 3 types in their entirety.

In 2004–05 number 12 was in Tallinna Trammi- ja Trollibussikoondis (TTTK) depot in Tallinn for large-scale repair/renovation process.

[2] In 1995 on conversion into the Spårakoff pub tram, number 175, ex-15, received a new all-red livery advertising Koff beer.

[10] During the extensive repairs at TTTK in Tallinn, number 9 and 12 have been painted with a modified version of the original livery, with added silver decorative stripes; one running between the yellow and green fields, and another near the bottom of the carriage.
