There have been a host of great Klingon episodes throughout the Star Trek franchise. From a few in the original, to bringing things to Chronos in Next Generation. Deep Space Nine got a lot more into Klingon culture when the war with Dominion started and Worf joined the cast. Voyager only ventured into Klingon-related episodes a couple of times, as they were pretty far removed from all Klingons except one. Here are the top 10 Klingon episodes in order.
# 10 The Emissary (NG)
A mysterious encounter with a Federation emissary. The Enterprise rushes to a probe location to pick up a half-Klingon / human female passing through K’Ehleyr.

K’Ehleyr wants to destroy the ship before it attacks the Federation outposts, but Captain Picard wants to avoid the kill. Worf and K’Ehleyr work together and have a heated argument and it doesn’t produce results. They find themselves on the holodeck and regain their romantic feelings. Worf wants to get married, but KEhleyr refuses and leaves. Worf comes up with a plan and receives control of the Enterprise from Captain Picard. Convince the Klingon Battlecruiser that the Federation is not at war. K’Ehleyr hints that he will return.

Problem # 1 with Tribbles
One of the funniest and funniest episodes of Star Trek to this day. The story begins with a priority distress call from a space station to the company. When Kirk heads to the space station, he discovers that the Klingons are already there. According to an agreement, the Klingons must be able to enter the station. Kirk reluctantly allows it, as long as there are the same number of Starfleet officers at all times. Things heat up when the Klingons start taunting the Enterprise and its crew. It turns into a hilarious brawl that ends the ‘vacation’ at the station. The true intent of the Klingons is discovered later in the episode from an unexpected source.
