Climbing! (also known as Mountain Climbing!) is the debut studio album by American hard rock band Mountain. The album was released on March 7, 1970, by Windfall Records. It peaked at No. 17 on the Billboard 200 chart, and spent 39 weeks on the chart.

The album included the group's best-known song, "Mississippi Queen", which became a hit, and "Never in My Life", which was regularly aired on contemporary FM radio. Both were sung by West, while Pappalardi supplied the vocal on another radio favorite, "Theme for an Imaginary Western".

The album was recorded at the Record Plant in New York City. Felix Pappalardi produced the album, while Bob d'Orleans engineered it.

In 1969, Leslie West recorded his debut solo album, titled Mountain, with Felix Pappalardi on bass and drummer Norman Smart. Smart was replaced by Corky Laing on drums and percussion, and keyboardist Steve Knight was added to form the classic Mountain lineup, with Pappalardi as producer.

Windfall Records released Climbing! on March 7, 1970. The album debuted at No. 186, and peaked at No. 17 on the Billboard 200 chart. The album was certified gold by the Recording Industry Association of America (RIAA) on August 28, 1970.

"Mississippi Queen" was the band's debut single, released in February 1970. The single peaked at No. 21 on the Billboard Hot 100 chart. "For Yasgur's Farm" was released as a single in August 1970. It peaked at No. 107 on the Billboard Bubbling Under Hot 100 chart. "Silver Paper" was also released as a single in 1971, but it failed to chart.

Classic Rock Magazine said: "Its organic, hard-driving blues rock owed a significant debt to Cream, who were produced by Mountain bassist/vocalist Felix Pappalardi."
