Villa Felicitas, Protected historic villa in Bad Ischl, Austria.

Villa Felicitas is a protected historic house in Bad Ischl that reflects 19th century alpine building traditions and stands as a testament to that era. The building preserves its original features and today functions as a guest house offering holiday apartments and dining facilities.

Eduard Mastalier, a Bad Ischl spa physician, built the house in 1855 as a guesthouse in alpine country-house style on a large park plot along the road to the Wolfgangsee, naming it "Villa Felicitas" ("country house of happiness"). It later passed to the Koch family, who ran Bad Ischl's Hotel Post. From 1889 until World War I, Burgtheater actress Katharina Schratt rented it for July and August to be near Franz Joseph I, who covered her costs; the house was then called "Villa Schratt".

The house's name means "country house of happiness". Guests here included actor Alexander Girardi and composer Johann Strauss (son); from 1964 opera singer Linda Plech ran it as a guesthouse with a seminar and concert room in the attic, continuing the house's role as a meeting point for artists.

The property is accessible as a guest house where visitors can explore the public areas and rooms. It is best to check in advance when the house can be viewed, as it continues to operate as an active guest house.

Franz Joseph had a wooden footbridge built so he could cross from the Kaiservilla park to the villa for breakfast; a gate in the park fence, which he unlocked and locked himself at 6.30 a.m., led to it. He is said to have called his stays here "the happiest hours".
