Sankt Johann in Tirol, called Sainihåns (German pronunciation: [zãɪ̯nɪ'ɦåns]) in the local dialect,[3] is a market municipality in the Kitzbühel district of Tyrol, Austria.

In the regional ductus, the last syllable of the name is stressed as "Sankt yo-Hahn'" (German pronunciation: [zaŋkt joˈhan]).

The town’s train station serves as a regional transport hub and several federal highways (Bundesstraßen) intersect in the municipality.

The municipality of St. Johann in Tirol includes the Weiler (hamlets) and Dörfer (villages) of Almdorf, Apfeldorf, Bärnstetten, Berglehen, Fricking, Hinterkaiser, Mitterndorf, Niederhofen, Oberhofen, Reitham, Rettenbach, Scheffau, Sperten, Taxa, Weiberndorf, Weitau, Winkl Schattseite, and Winkl Sonnseite.

This region was already settled in the 4th century BC by a Celtic tribe, the Ambisontiers, who pursued copper mining in the surrounding mountains.

Following the downfall of the West Roman Empire in 476 AD the region went to the Duchy of Bavaria in the 7th century in the wake of the European migrations and as result of the settlement of the Germanic tribe of the Bavarii.

In the 8th century (probably before 738), the missionaries built a Catholic church in the region of St. Johann, which was dedicated to St. John the Evangelist, from which the town's name was derived.

On 13 May 1954 the Tyrolean state government granted the following coat of arms to the municipality of St. Johann in Tirol: In a green and red vertically-divided shield are, on the right, an inverted, silver ibex horn and, on the left, a gold bishop's crozier.

With approximately 520,000 overnight stays per year, roughly evenly split between summer and winter, St. Johann is one of the major tourist resorts in the Tyrol.

In recent decades, St. Johann has experienced an economic boom in trade, services and light industry and it has become the shopping centre for the district of Kitzbühel.

Several firms are based in St. Johann, such as the headquarters of the Fritz Egger GmbH & Co, one of the best-known chip board manufacturers in Europe.

Today, the region around St. Johann in Tirol is one of the agricultural centres of Tyrol, despite its harsh climate and heavy precipitation.

Agriculture in the wide basin of the St. Johann bowl has a great tradition as the former breadbasket of Tyrol and, even today, farming continues to play an important role.

A relatively large number (for the Tyrol) of farms are established in the wide, level basin and on its fairly gently (with a few exceptions) slopes.

European route E641, which connects Wörgl with Salzburg, passes through St. Johann in Tirol, intersecting here with highway B161 to Mittersill.

In addition to electricity and natural gas there has also been an environmentally friendly district heating system since the end of 2008 which supplies the largest buildings in the village.

In 2009, 29 gigawatt-hours (100 TJ) of heating was purchased, that corresponds to an oil consumption of about 3.4 million litres (900 thousand US gallons) per year.

In the medium term the introduction of district heating in St. Johann will save about 12,000 tonnes of carbon dioxide annually in the village centre.
