Hämeenlinnan maalaiskunta (abbreviated as Hämeenlinnan mlk, Swedish: Tavastehus landskommun) is a former municipality of Finland in the former Häme Province, now in Tavastia Proper.

There was an Iron Age hillfort located in Luhtiala (Aulanko), which was demolished in the 13th century as the Häme Castle was built nearby.

The nearby hill, nowadays used for military training, is known as Hätilänvuori.

As Hämeenlinnan mlk was dissolved before the 8th of April, 1949 (when rural municipalities were allowed to adopt coats of arms), it never had an official coat of arms.

The artist Tapani Talari has designed an unofficial coat of arms[a] for Suomen Kuntaliitto ry.
