Rendezvous Days is an annual event in Eureka, Montana. It is a three-day festival designed to provide fun and entertainment to the whole family.

The Rendezvous Days celebrates the founding of the Tobacco Valley. According to local tradition, it was 1808 when the premier surveyor and mapping expert of the Northwest Trading Company, David Thompson, stumbled upon an area where the natives were growing tobacco on the banks of the river. From this, the neighboring settlements grew and became the current towns in the area.

The Rendezvous Days is one of the largest events in Northwestern Montana. Folks can enjoy live music, food, arts and crafts, antique car shows, flea market, cook offs, and several competitions. It is regularly held around late April to early May.
