Katrin, Mountain summit in Bad Ischl, Austria.

Katrin is a mountain near Bad Ischl with a summit reaching approximately 1,542 meters in elevation. From the top, you can see the northern Alps and the lakes of the Salzkammergut region.

In 1910 a cross honouring Emperor Franz Joseph I's 80th birthday was consecrated on the Elferkogel in front of about 500 onlookers. In 1955 a committee was formed to build a cable car, and after the line opened in 1959 it was rebuilt between 1976 and 1978 with 29 pylons and 46 four-person gondolas. Since 2011 the lift has run mainly in summer, with weekend winter service from 2014/2015.

Since 1995 the Katrinberglauf has been held annually, a 4,500 m race from the valley station at 474 m to the top station at 1,415 m, climbing 943 m. The course record of 31:14 minutes was set in 2006 by New Zealand's six-time mountain running world champion Jonathan Wyatt; Austria's Elisabeth Rust holds the women's record at 39:48 from 2000.

The Katrin-Seilbahn, a 4-seater circulating gondola with a slanted length of about 2,490 m, runs from Bad Ischl (474 m) up to the Katrin-Alm at roughly 1,415 m in 15 minutes. Since winter 2014/2015 it operates on Fridays, Saturdays and Sundays until the end of March. The 300 m Katrin-Klettersteig to the Kaiser-Franz-Joseph-Kreuz requires climbing equipment.

Since October 2019, a "confession gondola" blessed by Linz diocesan bishop Manfred Scheuer has run on the cable car: during the fifteen-minute ride to the mountain station, passengers can talk with a priest. The summit cross itself, the Kaiser-Franz-Josephs-Kreuz on the Elferkogel, was inaugurated on 17 August 1910 before about 500 onlookers for the emperor's 80th birthday and is lit by light bulbs in good weather.
