Trident Wolf Eclipse (stylized ·TRIDENT·WOLF·ECLIPSE·) is the sixth full-length studio album by Swedish black metal band Watain.

According to frontman Erik Danielsson, the album title should be read as three separate words which were chosen to represent symbolic concepts which the band consider central to their music.

"[2] Many of the lyrical themes which focus on empowerment and the attainment of force were influenced by the band's experience touring with Deströyer 666 in the years following the release of The Wild Hunt.

[3] On October 31, 2017, the band released "Nuclear Alchemy" as a single on 7-inch vinyl and digital formats, as well as a music video directed by Claudio Marino of Artax Film.

"[4] With regards to the five-year gap between the release of The Wild Hunt and Trident Wolf Eclipse, he has also stated that "we proceeded at our own pace and as a result broke our customary three-year cycle – which felt good, like the uprooting of all patterns eventually does.

Decibel described the album's sound as "harsh and austere", and wrote that "If The Wild Hunt was an epic and expansive attempt at the immortal, Trident Wolf Eclipse is all ritualistic and instinctive furies."

PopMatters gave a positive assessment of the album, writing that "despite the songs' uniformity and very minimal use of codas rich in aphotic atmospheres, there is serious songcraft to be found within the shifting ferocity Watain emphasize since it is extremely difficult to arrange jolting transitions to flow together seamlessly."

Stereogum praised the band's return to their earlier, more aggressive black metal style, writing that "This is easily the band’s most ruthlessly intense album since 2003 sophomore LP Casus Luciferi, and it may in fact be the gnarliest, weirdest, darkest thing they’ve ever made" and called it their "least accessible album, and the most exciting thing they’ve done in a decade.
